The line NO that is perpendicular to the plane mirror surface and drawn at the point of incidence is called the :

If an incident light ray is reflected back along its original path by a plane mirror, then its angle of incidence is:

The angle between incident ray and reflected ray is $$60^\circ{}$$. What is the value of angle of incidence?

The laws of reflection hold good for :

Which of the following statements is correct regarding rods and cones in the human eye?

Two mirrors A and B are placed at right angles to each other as shown in figure. A ray of light incident on mirror A at an angle of $$25^{\circ}$$ falls on mirror B after reflection. The angle of reflection for the ray reflected from mirror B would be :

In above figure, showing the refraction of light by a plane mirror. Which option is correct ?

Light is falling on surface S$$_{1}$$,S$$_{2}$$,S$$_{3}$$ as shown in the figure. Surfaces on which the angle of incidence is equal to the angle of reflection is/are :

A small hole P is made in a piece of cardboard. The hole is illuminated by a torch as shown in Fig. 16.3. The pencil of light coming out of the hole falls on a mirror.
At which point should the eye be placed so that the hole can be seen?

We can see a non-luminous object when light :
