Question

Plzzz tell this ques. 5
I will mark effective as brainliest answer

Answer 1

Answer: refraction of light:
1. the incident ray ,the reflected ray and the normal at the point of incidence ,all lie in in the same plane.
2. the ratio of sine of angle of incidence to the Sine of angle of refraction is constant for a given pair of media.
sine i/ sine r = constant

Answer 2

Laws of Refraction -

1. The incident ray, the refracted ray and the normal to the surface at the point of incidence are in the same plane.

2. The angle of incidence and the angle of refraction satisfy the equation - sin i/sin r = N2/N1.

Snell's Law - Sin i/sin r = n
