A mirror is inclined at an angle of theta with the horizontal. If a ray of light is incident at an angle of incidence theta then the reflected ray makes the following angle with the horizontal

What is meant by the 'angle of incidence' and the 'angle of refraction' for a ray of light? Draw a labelled ray diagram to show the angle of incidence and the angle of refraction for a refracted ray of light.

Study the following ray diagram : In this diagram, the angle of incidence, the angle of emergence and the angle of deviation respectively have been represented by .

A normally incident ray reflected at an angle of 90^(@) . The value of critical angle is

A ray of light is incident on a prism of refracting angle A. if theta_(C) is the critical angle for the material of the prism with respect to the surrounding air, then:

In the diagram shown, a ray of light is incident on the interface between 1 and 2 at angle slightly greater than critical angle. The light surfers total internal reflection at this interface. After that the light ray falls at the interface of 1 and 3, and again it suffers total internal reflection. Which of the following relations should hold true?
