Choose the correct option for the following Assertion (A) and Reason (R).

Question

G1 Physics · Accepted Answer

Each component progressive wave transports average energy in its direction of propagation. For a stationary wave, the two component waves have equal amplitude and travel in opposite directions. Hence their average powers are equal in magnitude and opposite in direction. The net average energy transport is therefore zero. Both Assertion and Reason are true, and the Reason correctly explains the Assertion. Correct option: A.
