D
velocity
2) The number of crests of a wave that move past a given point in a given unit of time.
A
period
B
frequency
C
amplitude
D
wavelength
3) When light stops at the object this is called
A
reflection
B
refraction
C
absorption
D
transmission
4) When light bounces off the surface of a material at an angle equal to the angle of the incoming light wave this is called
A
absorption
B
transmission
C
refraction
D
reflection
5) Why does the pitch of sound change when a police siren is behind you and then passes you?
A
sound waves only move in one direction; therefore, the pitch is altered
B
sound travels in all directions therefore the pitch changes
C
the pitch does not change
D
the distance between the source of sound and the observer is changing; therefore, wave frequency changes

A
Velocity includes how far an object has moved while speed is how fast an object is moving
B
velocity is how fast an object is moving while speed includes direction
C
None of these
