If the incident ray striking the reflecting surface is rotated by an angle of 30 degrees clockwise then reflected ray is rotated by an angle of?

If the angle of reflection with the normal is 30 degrees as shown in the figure, what is the angle made by the incident ray with the reflecting surface?

What is the angle of incidence of a ray if the reflected ray is at an angle of 90° to the incident ray?

if the incident ray is rotated clock wise by 30 degrees, and the mirror is rotated by 15 degrees in the anti - clock wise direction, then by what angle does the reflected ray rotate?

An incident ray makes an angle 35⁰ with the surface of a plane mirror. What is the angle ofreflection?

A plane mirror reflecting a ray of incident light is rotated through an angle  θ   about an axis through the point of incidence in the plane of the mirror perpendicular to the plane of incidence, thenSelect an answerAThe reflected ray does not rotateBThe reflected ray rotates through an angle  θ CThe reflected ray rotates through an angle 2 θ DAll are correct
