PhysicsMediummultiple choice

$P$ , $Q$ and $R$ are three particles of a medium which lie on the $x$ -axis. A sine wave of wavelength $λ$ is travelling through the medium in the $x$ -direction. $P$ and $Q$ always have the same speed, while $P$ and $R$ always have the same velocity. The minimum distance between:

Options:(select one or more)

Answer:

A, D

Solution:

Equal speed at all times means equal magnitude of velocity: the particles are in phase or in antiphase, so the minimum distance is $λ /2$ . Equal velocity means in phase, so the minimum distance is $λ$ .
