The angle between incident ray and reflected ray is `60^@`. What is the value of angle of oncidence?

The angle formed between the reflected ray and the normal is ------.

What should be the angle between two plane mirror so that whatever be the angle of incidence, the incident ray and the reflected ray from the two mirrors be parallel to each other

A ray light fall on a plane surface at an angle of incidence 9^@ and reflection occurs. Calculate the angle of reflection in degree.

A ray of light passes from denser medium to rarer medium a. What happens to the refracted ray as the angle of incidence increases from 0^(@) ? b. What is the importance of the angle C (marked in the figure above )? c. How is 'C' related to the refractive index 'n' of the medium ? Explain.

TRUE or FALSE: Incident ray and refracted rays are parallel to the normal.
