Question

Define reflection of light and condition of reflection

Answer 1

Answer:

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface.

For total internal reflection to occur, two conditions must be met: The index of refraction must decrease across the boundary in the direction of light refraction. The angle of incidence of the light ray must exceed the critical angle of the interface. Ray must travel from denser to rarer medium.

Answer 2

Reflection of light occurs when light touch on a surface and bounce back.

In smooth surface,

incident angle = reflected angle

and

all lie in same plane.
