Total questions: 10
Worksheet time: 5mins
What type of wave interference is shown in the diagram?
The diagram shows two original waves interfering with each other to produce a combined waveform. The two original waves, shown on the left side of the image, are:
During constructive interference, two waves moving through the same medium will
amplify each other
move around each other
cancel each other out
A standing wave is a wave that appears fixed or stationary in space.
True
False
Under the Doppler Effect, an observer behind a moving wave source observes
increased wave frequency
no wave frequency
decreased wave frequency
unchanging wave frequency
Police radar works to detect speeding cars by use of
wave interference
the Doppler Effect
the formation of standing waves
wave canellation
When refraction occurs, a change in wave speed leads to a change in wave direction.
True
False
Reflection occurs with light waves but not with sound or water waves.
True
False
Another name for destructive interference is
cancellation
amplification
standing
antinode
When the source of a wave is moving relative to an observer of the wave, which of the following is true?
observers ahead of the wave observe an apparent increase in wave frequency
observers both ahead of and behind the wave notice an increase in frequency
observers in all directions notice a decrease in wave frequency
observers behind the wave observe lower wavelengths and higher frequency
