Wave Phenomena

Front

absorption

Back

when a wave transmits its energy to a medium

Front

reflection

Back

occurs when a wave bounces back after hitting a surface

Front

refraction

Back

the bending of waves as they pass through a medium

Front

diffraction

Back

occurs when a wave changes direction or bends when it hits an obstacle

Front

constructive interference

Back

when the crest and trough of waves meet and combine to form one larger wave

Front

destructive interference

Back

when the crest of one wave meets the trough of another wave resulting in a smaller wave with lower amplitude

Front

resonance

Back

occurs when the sound produced by one object causes another to vibrate, making a louder sound

Front

standing waves

Back

when two waves combine and look like they are standing still, but are not

Front

the doppler effect

Back

the change in frequency of a wave as the source of the wave is in motion
