Huygen's theory of secondary waves can be used of find
Velocity of light
The wavelength of light
Wave front geometrically
Magnifying power of microscope
Wavefront of a wave has direction with wave motion
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 :
Explain refraction of plane wave with a thin prism.
When a plane wave front incident on a concave mirror as shown in figure then shape of reflected wave front
Wave front is locus of all the points where the particles of the medium vibrate with the same
