A light ray is incident on a plane mirror with ${30}^o$ angle of incidence. What will be the angle of reflection?

Q. A light ray is incident normally on a plane mirror. The angle of reflection will be :

Q. A ray of light is incident on a horizontal plane mirror at an angle of incidence ${30}^o$. By what angle should the mirror be rotated so that the reflected ray becomes horizontal?

Q. If a ray of light is incident on a plane mirror at an angle of 30º with the mirror, what will be the angle of reflection?

Q. If a ray of light incident on a plane mirror is such that it makes an angle of ${30}^o$ with the mirror, then the angle of reflection is:
