Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
Standing waves are produced by
Two equal waves travelling in opposite directions
Two waves in the same direction
Waves of different frequency
A single wave with no reflection
2.
Adjacent nodes in a standing wave are separated by
λ
λ/4
2λ
λ/2
3.
A standing wave has nodes 0.40 m apart and a frequency of 50 Hz. The wave speed is
20 m s−1
10 m s−1
40 m s−1
80 m s−1
4.
Which statement about a standing wave is correct?
Energy flows steadily from node to antinode
Points between adjacent nodes are in phase
All points have the same amplitude
Wavelength equals node spacing
5.
At a node the displacement is
Always zero
Zero only at one instant
Maximum
Twice the amplitude
6.
Compared with a travelling wave, a standing wave has
Greater speed
Higher frequency
Equal amplitude at all points
No energy transfer along the medium
