Question

In case of mechanical wave a particle oscillates and during oscillation its kinetic energy and potential energy changes.

Answer 1

A) When particle of travelling wave is passing through mean position then KE is maximum and PE is minimum

B) When particle of travelling wave is at extreme position then KE is min and PE is max

C) When particle between node and antinode in standing wave is passing through mean position then KE is max and PE is min

D) When particle between node and antinode in standing wave is at extreme position then PE is max and KE is min
