Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Reflection in all types of mirrors is governed by ____ principal laws.
A
2
B
3
C
4
D
5
Explanation: 

Detailed explanation-1: -The second law of reflection states that “the incident ray, the normal to the surface at the point of incidence and the reflected ray, all lie in the same plane”.

Detailed explanation-2: -Hint:Reflection of light from a reflecting surface can be of two types – regular reflection or irregular reflection. Diffused reflection refers to irregular reflection which is caused due to the irregularities of the reflecting surface. The laws of reflection will be obeyed in all kinds of reflection.

Detailed explanation-3: -The laws of reflection are valid for any reflecting surface including spherical surfaces. So, they are valid for both plane and curved mirrors.

Detailed explanation-4: -Laws of reflection states that: The incident ray, the reflected ray and the normal at the point of incidence all lie in the same plane. Angle of incidence is equal to the angle of reflection.

Detailed explanation-5: -A mirror illuminated by many parallel rays reflects them in only one direction, since its surface is very smooth. Only the observer at a particular angle will see the reflected light. The law of reflection is very simple: The angle of reflection equals the angle of incidence.
