Question

Define progressive wave and plane progressive wave

Answer 1

A wave which travels continuously in a medium in the same direction without any change in its amplitude is called aprogressive wave or a traveling wave. Aprogressive wave may be transverse or longitudinal in nature.Suppose that a planesimple harmonic wave travels from origin O along the positive direction of X-axis.

Waves move energy from one place to another. In a progressive wave the wave front moves through the medium. There are two types of waves, transverse and longitudinal. Transverse waves are waves where the displacement of the particles in the medium is perpendicular to the direction the wave is travelling in.
