Huygen wave theory allows us to know
The wavelength of the wave
The velocity of the wave
The amplitude of the wave
The propagation of wave fronts
(d)Huygen’s theory explains propagation of wavefront.
On a hot summer night, the refractive index of air is smallest near the ground and increases with height from the ground. When a light beam is directed horizontally, the Huygens' principle leads us to conclude that as it travels, the light beam
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
Which one of the following phenomena is not explained by Huygen's construction of wavefront
By Huygen's wave theory of light, we cannot explain the phenomenon of
What is the most important point of Huygen's wave theory ?
