Question

Statement 1: Angle of incidence is always equal to the angle of reflection.

Statement 2: Angle of incidence is always twice the angle of reflection.

Statement 3: The incident ray, reflected ray and the normal all lie in 3 different planes.

Statement 4: The incidence ray, reflected ray and the normal all lie in the same plane.

Which of the statements refer to the laws of reflection?

• A. 1 & 4
• B. 2 & 3
• C. 1 & 3
• D. 2 & 4

Answer 1

The correct option is A

1 & 4

Reflection is the change in direction of the wavefront at an interface between two different media. There are mainly two types of reflection that are diffuse and multiple reflections. Laws of reflection states that:

1. The angle of incidence = Angle of reflection. It is generally expressed in $\theta$.

2. The incident ray reflected ray, the angle of incidence, the angle of reflection and normal all lie in the same plane.
