What is a refracted wave? $OR$ What is a stationary wave?
(N/A) $1$. Refracted wave: When a wave travels from one medium to another,its direction changes due to a change in speed. This phenomenon is called refraction,and the wave in the second medium is known as the refracted wave.
$2$. Stationary wave: $A$ stationary wave (or standing wave) is formed by the superposition of two identical waves traveling in opposite directions in the same medium. In this wave,the disturbance does not propagate through the medium,and the energy is not transferred from one point to another. Points of zero amplitude are called nodes,and points of maximum amplitude are called antinodes.
