Question

I have a dought about that how light is reflected
And how are reflection happens and refraction happens

Answer 1

Answer:

Explanation:

Light is reflected when there is a mismatch between materials through which the light is travelling. ... Normally the index of refraction is used to determine the angle that light propagates in a material when it "bends" or refracts, but we can also use it to calculate how much light reflects.

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction.

Hope it helps

Answer 2

Hey, here we go

Reflection is bouncing off of light from smooth surface.

Reflection only occurs when the surface is very much smooth.

Laws of reflection are as follows,

The angle of incidence is equal to angle of reflection.

The normal the incident ray and the reflected ray lie on a same point on O.

whereas refraction is the refracting of the rays of a light when it travels from one medium to another medium.

When rays of light travels from rarer medium to denser medium it bend towards.

when the rays of light travel from denser medium to rarer medium it travels away from the normal.
