Solution

The correct option is C 3 and 4
According to the laws of reflection:
1. The angle of incidence is equal to the angle of reflection.
2. The incident ray, the normal at the point of incidence and the reflected ray all lie in the same plane.

Laws of reflection are valid whenever reflection of light occurs.

Suppose you have a plane mirror that reflects light. When light strikes the mirror, the light is reflected off the surface. The law of reflection says that:

Statement 1: The angle of incidence (incoming ray) is equal to the angle of reflection (outgoing ray).

Statement 2: The angle is measured from a perpendicular line to the surface called as Normal.

Statement 3: Incident ray, reflected ray and the normal does not lie in the same plane.

Statement 4: The law works for the plane as well as for curved surfaces.

Q. Explain the following terms- Incident ray, reflected ray, angle of incidence, angle of reflection, normal.

The angle of incidence and angle of reflection are equal only if the incident ray and the reflected ray are in the same plane and the normal is in a different plane.
