Chapters 10 and 11 quiz

What type of waves are these?

A B

1

Matching - Wave properties

A. WavelengthB. FrequencyC. AmplitudeD. Speed

1. the number of wave crests which pass a point per second

2. the rate at which the wave travels away from the source

3. the distance between similar parts of a wave

4. the maximum amount the medium is disturbed from equilibrium

2

Wave Properties: Speed

The speed of sound is 1/5 mile/sec

You hear the thunder 10 seconds after seeing the lightning.

How many meters away is the lightening?

3

If you cut the wavelength in half and the speed stays the same, the frequency will

a) Doubleb) Be cut in halfc) Quadrupled) Remain unchanged

Speed = frequency × wavelength

4

Matching – Crude wave behavior descriptions

A. ReflectionB. RefractionC. DiffractionD. Interference

1. Bending when the medium changes

2. Bouncing off an interface3. Combining waves to

strengthen or weaken the total wave

4. Bending around corners

5

T/F A wave diffracts much more when the

incoming wavelength is much smaller than the opening.

6

Electron Source

Electromagnetic radiation is given off whenever electrons __________.

7

Wave Particle Duality

Why is light both like a wave and a particle?
