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) reflection

c) absorption
d) transmission
Why does the pitch of sound change when a police siren is behind you and then passes you?
a) the pitch does not change
b) sound travels in all directions therefore the pitch changes
c) the distance between the source of sound and the observer is changing; therefore, wave frequency changes
d) sound waves only move in one direction; therefore, the pitch is altered
