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 |
