1
Q
reflection
A
the bouncing back of a wave as it meets a surface it cant pass through
2
Q
what does NOT get changed when a wave is reflected?
A
speed or frequency
3
Q
refraction (broken straw in glass)
A
the bending of a wave as it enters a new medium at an angle
4
Q
diffraction
A
bending of a wave as it moves around an obstacle or passes through a narrow opening
5
Q
constructive interference
A
when 2 or more waves combine to produce a wave with a LARGER displacement
6
Q
destructive interference
A
when 2 or more waves combine to produce a wave with a SMALLER displacement
7
Q
standing wave
A
a wave that appears to stay in one place, does not move energy through
8
Q
what is a standing wave caused by
A
interference between a wave and its reflection
