A standing wave is produced on a string clamped at one end and free at the other. The length of the string

Two particles A and B have a phase difference of π when a sine wave passes through the region.

A wave is represented by the equation

y = (0001 mm) sin[(50 s⁻¹) t + (20 m⁻¹)x]

Mark out the correct options.

In a stationary wave,
