The angle formed by incident ray with normal is known as angle of incidence. _____

Fig. shows an incident ray AO and the normal ON on a plane mirror. The angle which the incident ray AO makes with mirror is 30^@ . Find the angle of incidence.

If the following figure, if the angle between the mirror and incident ray is 60^@ find angle of incidence

A ray of light passes from glass, having a refractive index of 1.6, to air. The angle of incidence for which the angle of refraction is twice the angle of incidence is

In the figure given the angle between incident ray and the reflected ray is 70^@ Find the angle of incidence.

A ray of light passes from vaccum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction, then the angle of incidence is

How does the angle of deviation formed by a prism change with the increase in the angle of incidence ? Draw a graph showing the variation in the angle of deviation with the angle of incidence at a prism surface.

Draw a diagram to show the reflection of a ray of light by a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.

In the following figures, draw the normal at the point of incidence and then find out its angle of incidence and angle of reflection

A light ray is incident normally on a plane mirror. What is its angle of incidence?

The following diagram (Fig) shows an incident ray AO and the normal ON on a plane mirror. Find the angle of incidence and angle of reflection.
