Question

define reflection of light. write two law of reflection ​

Answer 1

hey mate ❤

reflection of light is the phenomenon of bouncing back of light in the same medium on striking the surface of any object. ....

there are two laws of reflections

---1st law :states that the incident ray, reflected ray and normal all lie on same plane

2nd law :states that the angle of incident is always equal to the angle of reflection. .....

hope u understand

plz FOLLOW me..

and mark it as brainliest ✌ ✌ ✌.

Answer 2

The Laws of Reflection govern the reflection of light-rays off smooth conducting surfaces, such as polished metal or metal-coated glass mirrors.

Consider a light-ray incident on a plane mirror, as shown in attachment

The Laws of Reflection state are

1. The incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.

2. The angle of incidence i = the angle of reflection r. Both angles are measured with respect to the normal to the mirror.
