In year 12, we model satellite motion as uniform circular motion. We can account

for this in our equations:

Σ𝐹 =𝑚𝑣2

𝑅=𝐺𝑀𝑚

𝑅2= 𝐹𝑔

Σ𝐹 =𝑚𝑣2

𝑅=4𝜋2𝑅

𝑇2=𝐺𝑀𝑚

Charged Particles Moving Through a

Magnetic Field

19

A moving charge in a magnetic field will experience a magnetic force. This

force can be calculated from the equation

𝐹 = 𝑞𝑣𝐵From Newton’s second law, we know that whenever there is a net force, there

is an acceleration. Since there is a net magnetic force on a moving charge

through the magnetic field, it must be accelerating.

In reality, a moving charge does not change speed through a magnetic field –

it changes direction. Therefore, charged particles experience a centripetal

acceleration when they move through a magnetic field.

This yields the equation

𝑚𝑣2

𝑅= 𝑞𝑣𝐵

The direction of the magnetic force on a charged particle can be calculated

using the right-hand slap rule, except this time, the thumb points in the

direction of the charge’s velocity instead of in the direction of the current.

If the charge is negative, the thumb points in the opposite direction to the

charge’s velocity.

Weight Force/ Normal Force In

Satellites

21

2016 Physics Exam

• It is possible to experience weightlessness without being truly

weightless

• This occurs when the normal force acting on someone is 0 i.e

they are in freefall

• This gives them the sensation of being weightless, known as

apparent weightlessness

• Thus Emily is incorrect – it IS possible to FEEL weightless without

needing to be in deep space

Making calculations about an electrical generator (such as calculating the

average power it produces) can be tricky because induced EMF is always

varying.

To compensate for this, physicists sometimes like to use a quantity called

the root mean square or RMS voltage.

This is the DC voltage it would take to produce the same average power as

an oscillating AC voltage.

To find the RMS voltage, we use the formula

𝑉𝑅𝑀𝑆 =𝑉𝑝

2

𝑉𝑝𝑒𝑎𝑘 is the ‘peak’ voltage or the maximum voltage induced (this can be

read from a graph or an oscilloscope).

Transmission of Electricity

29

• Transformers significantly increases voltages to very high levels

• For a constant power, the voltage and the current are inversely

proportional (P = IV)

• An increase in voltage causes a decrease in current

• Decreasing the current decreases the power loss (𝑃𝑙𝑜𝑠𝑠 = 𝐼2𝑅), thereby reducing transmission losses

When working through banked track problems, here are some

useful tips when through these types of questions:

• Draw a diagram (if one isn’t already supplied to you)

• Draw a force triangle. Again, the only forces acting on the

car that is moving at the design speed should be the weight

force and the normal force

• Note that for many questions, you won’t actually need the

mass of the car to find the answer

• Why did the experiments

observe more muons

than expected?

• Because the half-life of

the muons, relative to the

experimenters, increased.

• This led to a higher

number of muons

reaching the detector

without decaying

The Doppler Effect

43

Emily is waiting to cross the road when an ambulance swerves around the corner with its sirens blaring. When the ambulance rushes towards Emily, the pitch of the siren seems to increase. As the ambulance passes Emily and drives into the distance, the pitch of the siren seems to decrease. Explain this effect.

• The change in pitch of the siren is due to the Doppler Effect

• As the ambulance approaches Emily, each consecutive sound

wave produced by the siren is slightly closer to her than the one

before, creating an apparent increase in frequency.

• Conversely, when the ambulance drives away from Emily, each

consecutive sound wave is slightly further away from Emily that

the one before, causing the apparent frequency to decrease.

• This causes the change in pitch of the siren that Emily hears.

Resonance

44

A wine goblet is able to shatter when certain frequencies of sound impinge upon it. Explain how this is possible.

• When sound with a frequency equal to the natural frequency of the

wine glass impinges on the goblet, resonance occurs.

• During resonance, all the energy from the source of the sound is

transferred to the wine glass. If enough energy is supplied by the

source, the glass’ vibrations become too large, causing it to shatter.

Standing Waves

45

A pipe organ can be modelled as a tube open at one end and closed at the other. If the length of one particular pipe organ is 1.5 m, calculate the frequency of the fourth harmonic the organ can produce. Assume the speed of sound in the organ is equal to 343 m s-1.

Polarization

46

Polarizing sunglasses are popular amongst athletes in winter sports as they help reduce glare and improve vision. Explain how polarizing sunglasses do this.

• Polarizing sunglasses restrict the light waves entering the lens so

that only light waves with a certain orientation are able to pass

through.

• Light waves that do not have the correct orientation are blocked,

which is what helps to reduce glare for the sunglass users.

Refraction

47

During a pool party in the evening, Betty turns the underwater lights on at the bottom of her pool to help her guests see where they are swimming. At some angles, the light is refracted in such a way at the water-air interface that it becomes parallel to the surface of the pool. What is this angle? Assume nwater = 1.33

Dispersion

48

When white light is passed through a glass prism, it ‘splits’ into its component colors. Identify this physics phenomenon and explain why it occurs.

• Every colour of light undergoes refraction to a slightly different

extent due to the differences in wavelength.

• White light is composed of all the colours of the visible spectrum.

• When it is passed through a glass prism, all the component

colours of white light refract to a slightly different extent.

• This causes the white light to ‘split’ and is known as dispersion.

Young’s Double-Slit Experiment

502015 Physics Exam

• The distance between the central band and each of the slits is the

same. Therefore, the path difference to the central band is 0.

• The path difference can only be 0 if it is of the form n𝜆 – not (n −0.5)𝜆.

• Since n𝜆 corresponds to constructive interference, the central band on

the screen must be a bright band

Young’s Double-Slit Experiment

51

2013 Physics Exam

• The appearance of the diffraction pattern of the screen in Young’s Double-Slit

experiment proves that light is able to undergo constructive and destructive

interference

• Interference is strictly a wave phenomena – it cannot be exhibited by particles.

• Therefore, Young’s Double-Slit experiment provides evidence for the wave

model of light – not the particle model. The statement is incorrect.

The Photoelectric Effect

54

• The wave model of light predicts that increasing the intensity of the light

increases the amount of energy supplied to the electrons, allowing them to

escape from the metal plate. However, this did not happen.

• The particle model for light predicts that increasing the intensity of light

increases the number of photoelectrons released, not their energy. So there is

still not enough energy to release electrons from the metal plate.

Observations vs Predictions

THE PHOTOELECTRIC EFFECT

55

Observations

1. There is a frequency called the

threshold frequency, f0, that

below which, there will be no

photoelectrons emitted.

2. Increasing the intensity of light

increases the number of

photoelectrons released.

3. Photoelectrons are released

instantaneously.

Predictions

1. All frequencies of light should

eventually be able to emit

photoelectrons

2. Increasing the intensity of light

increases the kinetic energy of

released photoelectrons

3. Photoelectrons are released

with some time delay

De Broglie’s Mode of the Atom

59

2014 Physics Exam

• Electrons are only stable is they form standing waves around the nucleus of

an atom.

• There are only some wavelengths of an electron matter wave that can form

standing wave

• As a result, there are only certain energy levels that an atom can occupy; -

the energy of atoms is quantized.

HEISENBERG’S UNCERTAINTY

PRINCIPLE

60

• Increasing the slit width will increase the range of possible positions the photon could be in as

it passes through the slit; it increases Δ𝑥.

• By Heisenberg’s Uncertainty Principle, an increase in Δ𝑥 will result in a decrease in Δ𝑝 (Δ𝑥

Δ𝑝 ≥ℎ

4𝜋)

• An increase in the uncertainty in momentum means that photons have a higher chance of

passing through the slit at wider angles. This effectively increases the width of the diffraction

pattern on the screen.

Before the Exam

63

Page 60: VCE Physics Units 3&4 Exam Revision LectureVCE Physics Units 3&4 Presented by: ALEVINE MAGILA Exam Revision Lecture • Introduction • How do things move without contact? • How

• You don’t have to do the exam in chronological order. In some cases, it

may be better to start with your strongest area of study. This leaves you

more time during the exam to focus on your weaker areas.

• Aim for a minute a mark. You want left over time at the end to check

over all your answers

• Never stop checking your work. If you have time at the end, then do not

stop checking your work until the time for the exam has ended

• If there’s a question that you’ve spent more that two minutes looking at

but still don’t know how to do – skip it. Your time is better spent

finishing the exam and then coming back to it later

• NEVER, ever leave anything blank. If you’re nearly finished and there

are still a few questions that your not sure how to do, take a guess!

Never leave any questions blank
