PhysicsMediummultiple choice

A sinusoidal wave $y_{i} = a sin (ω t - k x)$ is reflected from a rigid support and the reflected wave superposes with the incident wave. Assume the rigid support to be at $x = 0$ :

Options:(select one or more)

Answer:

B, C

Solution:

A rigid support gives a phase change of $π$ , so $x = 0$ is a node. The resultant $- 2 a sin k x cos ω t$ has an amplitude (and intensity) that varies with $x$ . At a given $x$ the amplitude does not change with time.
