addition of two or more waves when wave crests overlap to produce a resulting wave of increased amplitude. constructive interference
combination of waves where crests of one wave overlap troughs of another, resulting in a wave of decresed amplitiude destructive interfernence
term applied to two waves for which the crest of one wave arrives at a point at the same that a trough of the second wave arrives. Their effects cancel each other. out of phase
term applied to two or more waves whose crests and troughs arrive at a place at the same time, so that their effects reinforce each other. in phase
wave in which parts of the wave remian stationary and the wave appears not to be traveling. the result of interference between an incident orginial wave and a reflected wave. standing wave
any part of a standing wave that remains stationary. node
the positions on a standing wave where the largest amplitudes occur. antinodes
the apparent change in frequency of a wave due to the motion of the source or of the reciever. doppler effect
an increase in the measured frequency of light from apporaching source; called the blue shift because the apparent increase is toward the high frequency or blue end of color spectrum. also occurs when an observer approaches a source. blue shift
a decrease in the measured frequency of light or other radaition from a receding source, called the red shift because the decrease is toward the low frequency, or red, end of the color spectrum red shift
the v-shaped wave produced by object moving on a liquid surface faster than the wave speed. bow wave
a cone-shaped wave produced by an object moving at supersonic speed through a fluid. shock wave
the sharp crack heard when the shock wave that sweeps behind a supersonic aircraft reaches the listener. sonic boom
