Problem

Assertion : In a standing wave

x = 0

is a node. Then, total mechanical energy lying between

x = 0

and

x = \frac{\lambda}{8}

is not equal to the energy lying between

x = \frac{\lambda}{8}

and

x = \frac{\lambda}{4}

. Reason : In standing waves different particles oscillate with different amplitudes.
