Terms:
Direct relationship- A relationship where a increase or decrease
change in one variable causes the same kind of change in another
variable. For example: When I increase the speed at which I run, I
increase the distance I run. When I decrease how many calories I
eat, I decrease my weight. Science Research Terms
Inverse Relationship- When I increase/decrease one variable, I
cause the opposite change in another variable. Ex: When I increase
how much I exercise, I decrease my body fat. Think and Discuss
Discuss the following questions with your team:
What are wavelength and frequency? What is the relationship between
wavelength and frequency? Does a waves energy depend more on its
wavelength or on its frequency? Concept: Frequency Frequency is
measured in kilohertz (kHz).
A kilohertz is 1000 hertz, which is a measurement of cycles per
second. This means that a wave with a frequency of 1 kHz passes a
point 1000 times in 1 second. Apply: If a radio wave has a
frequency of 3 kHz and a gamma ray has a frequency of 3 x 1019 kHz,
how many more times does a gamma ray hit a point in 1 second? Which
wave do you think has a longer wavelength? Gamma Radiation People
who read Marvel Comics know that the Incredible Hulk was created
when a man was exposed to gamma rays. A real person exposed to
gamma radiation from nuclear waste would be badly burned. In the
Universe, gamma rays are released when a star turns on. Activity
Using a Slinkee, see if it takes more energy to produce a wave with
greater frequency. Concept: Wavelength Wavelengths are measured in
meters. They are measured from crest to crest or from trough to
trough. If infrared radiation has a wavelength of 10-4m and
microwaves have a wavelength of 10-2m, how many times longer is an
infrared wave than a microwave? Which wave has more energy?
Activity Using a Slinkee, see if low energy produces a longer or a
shorter wavelength. Concept: Amplitude Amplitude is a measurement
of the size of a waves average displacement from its centerline to
its crest. It describes a waves energy or intensity when its
compared to waves of the same wavelength and frequency. Investigate
