Reflection of Light

What is incident ray?

• the ray which forms 90 degree with surface

• the ray which passes through the surface

• the ray which strikes any surface

• the ray which is deflected by a smooth surface

What is the reflected ray?

• The ray which forms 90 degree angle with the surface

• The ray which gets deflected from the surface

• The ray which passes through the surface

• The ray which strikes the surface
