If the angle of incidence on a plane mirror is `30^(@)`, then angle between the reflected ray and the plane mirror is _____

Text Solution

Verified by Experts

The correct Answer is:
`60^@`
If the angle of incidence is `30^@` , the angle of reflection is also `30^@` . The angle between the normal line and plane mirror is `90^@` . So, the angle between reflected ray and the plane mirror is `90^@ - 30^@ = 60^@`

If angle fo incidence of a light ray on a plane mirror is 30^(@) , then

An incident ray strikes a plane mirror at an angle of 15^@ with the mirror. The angle between the reflected ray and the mirror is

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.

A ray of light is incident at an angle of 35^@ on a plane mirror. What is the angle between the incident and the reflected rays ?
