Is Huygen's principle valid for longitudunal sound waves ?
Yes, Huygen's principle is true and valid for all types of waves.
A plane wavefront travelling in a straight line in vacuum encounters a medium of refractive index $\mu$. At $P,$ the shape of the wavefront is :
Wavefront of a wave has direction with wave motion
A light beam is incident on a denser medium whose refractive index is $1.414$ at an angle of incidence $45^o$ . Find the ratio of width of refracted beam in a medium to the width of the incident beam in air
What is visible light ? Write various view on it.
A plane wave passes through a convex lens. The geometrical shape of the wavefront that emerges is
