Huygen's principle is used to

Huygens principle

Huygen's principle help us to find the shape of a wave front emitting from a source. draw the wave front for different source

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 Huygen's principle leads us to conclude that as it travels the light beam

One can use Huygen's principle to

Huygen's principle allows us to determine,

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 1......

State Huygens' principle and use it to describe the process of reflection of a parallel beam of light incident on a plane mirror obliquely with the help of a labelled diagram.Prove that the angle of incidence is equal to the angle of reflection.
