Question 23
SoundIn which of the following diagrams is the length of the tube equal to one wavelength?
- A.A
- B.B
- C.C
- D.D
Show the answer and explanation
Answer: C (C)
Explanation
Each loop of a stationary-wave pattern (node to node) is half a wavelength, so the tube is one wavelength long when it holds two complete half-wave loops between antinodes at the open ends, as in C.
