alleryTwo waves of the same amplitude and frequency travel in opposite directions along the same line and superpose. What is formed?
AA shock wave
BA standing wave
CA damped wave
DA pulse with zero frequency
Answer & Solution
Correct answer: B. A standing wave
A standing wave is formed when two identical waves travel in opposite directions and superpose.
The resulting pattern has nodes and antinodes and no net transfer of energy along the medium.
