Question

What is meant by 'refection of light'? Define the following terms
used in the study of refection of light by
drawing a labelled ray-diagram :
(a) Incident ray (b) Point of incidence: (c) Normal: (d) Reflected
ray: e) Angle of incidence:
(f) Angle of refection:
​

Answer 1

Answer:

bouncing back of light is called reflection

a) the ray which strikes the reflecting surface

c) the perpendicular drawn from the point of incidence

e) the angle formed between normal and incidence ray

f) the angle formed between normal and reflected Ray

Answer 2

Reflection of light is 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. This is called specular reflection.

An incident ray is a ray of light that strikes a surface

ingeometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal.

Reflected ray means An incident ray is a ray of light that strikes a surface.

the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence

The angle of reflection of a ray or beam is the angle measured from the reflected ray to the surface normal
