Assertion : Velocity of particles, while crossing mean position (in stationary waves) varies from maximum at antinodes to zero at nodes.Reason:Amplitude of vibration is maximum at antinodes and at nodes amplitude is zero and all the particles between two successive nodes across the mean position together.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

A

Explanation

Stationary wave

A node is a place of zero amplitude and an antinode is a place of maximum amplitude.
