Q1115
A standing wave occurs when
A.
A wave reflects upon itself
AnswerB.
The amplitude of a wave exceeds its wavelength
C.
Two waves overlap
D.
The speed of the wave is zero or near zero
Answer: Option A
Solution
Answer: Option A
Solution:
In a bounded medium, standing waves occur when a wave with the correct wavelength meets its reflection. The interference of these two waves produces a resultant wave that does not appear to move. Standing waves don't form under just any circumstances.
