What is the physical environment that waves occur in?
medium

What is the measure of how high or how low a wave sounds?
pitch
200
What is the bending of a light wave as it passes from one medium into a different medium?
refraction
200
What is the speed that waves travel at?
frequency
300
What are waves the require a medium (such as sound)?
mechanical waves
300
What is the distance from a point on one wave to the same point on the next wave?
wavelength
300
What determines how loud or soft a sound is?
amplitude
300
What electromagnetic waves have the highest frequency?
gamma rays
300
What determines what color of visible light we see?
the frequency of the wave
400
What are waves where the particles move perpendicular to the direction of motion?
transverse waves
400
What is the distance (how high or how low) particles move from the baseline of the wave?

400
What determines the pitch of a sound?
the frequency of the wave
400
What type of electromagnetic wave has the longest wavelength?
sound waves
400
What is the law of reflection?

earth/dirt
500
What is the time it takes for a wave to complete one cycle?

500
What causes sound waves?

500
Why does light have a "dual nature?"
it can behave as waves or particles

What is the difference between a concave and a convex mirror?
Concave curves inward and compresses the image. Convex curves outward and stretches out the image.
