Statement-1 : A ray incident along normal to the mirror retraces its path. Statement-2 : In reflection, angle of incidence is always equal to angle of reflection

If both Statement- I and Statement- II are true, and Statement - II is the correct explanation of Statement– I.

If both Statement - I and Statement - II are true but Statement - II is not the correct explanation of Statement – I.

If Statement - I is true but Statement - II is false.

If Statement - I is false but Statement - II is true.

A ray of light is incident on a plane mirror, making an angle 'q' with the surface of the mirror. Arrange the following steps in sequential order to calculate the angle between the incident light ray and the reflected light ray. (A) Draw a normal line on the plane mirror at the point of incidence of the light ray. (B) Note down the angle between the plane mirror and the incident light ray. (C) The sum of the angle of incidence and the angle between the plane mirror and the incident ray is 90^@ . Determine the angle of incidence. (D) From the laws of reflection, the angle of incidence is equal to the angle of reflection. Then the sum of the angle of incidence and the angle of reflection gives the angle between the incident light ray and the reflected light ray.
