Question

Define reflection, its type and laws of the reflection

Answer 1

Reflection: The bouncing off of light after falling on an object's surface is called reflection of light.

Types: It is of two types: Regular reflection and Irregular reflection.

Regular Reflection: When the light rays fall parallel on a smooth and shiny surface like mirror, then the reflected rays are parallel as well. This type of reflection is called regular reflection.

Irregular Reflection: When the light rays fall parallel on a rough and dull surface like cardboard, then the reflected rays are not parallel. This type of reflection is called irregular reflection or diffused reflection.

The laws of reflection: The two laws of reflection are:

• The incident ray and the reflected ray are always equal. Therefore, angle I = angle R.
• The incident ray, the reflected ray, the point of incidence, and the normal all lie on the same point on the same plane.

Answer 2

Answer࿐

Laws of reflection:-

1st law:-The incident ray, the reflected ray,and the normal at the point of incidence lie on the same plane.

2nd law:- The angle of incidence is equal to the angle of reflection.
