Standing waves can be set up in a string when two waves that are
A) of the same frequency and amplitude, but are opposite in direction of travel, meet each other.
B) of the same frequency, amplitude, and direction of travel are also 180° out of phase.
C) of the same frequency, amplitude, and direction of travel meet each other.
D) of the same frequency, amplitude, and velocity meet each other.

Question

Quizplus · Accepted Answer

Standing waves are formed when two waves of the same frequency and amplitude, traveling in opposite directions, meet and interfere with each other. This results in points of no displacement (nodes) and points of maximum displacement (antinodes) along the string.
