Question

1. What are laws of reflection and refraction?
​

Answer 1

Answer:

The law of reflection states that the incident ray , reflected ray and the normal to the surface if mirror all lie in the same plane. the angle of reflection is equal to angle of incidence . Both angle are measured with respect to normal to mirror....

Law of refraction state that : the incident ray , reflected ray and normal to the interface of any two given medium , all lie in the same plane . The ratio of sine of angle of incidence and sine of that angle of refraction is constant...... plz follow me....

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.
