Answer 1

hey Frnd,

I am meritkshitij here.

ur answer goes like this,

(70) ans.laws of refraction that defines it is

the ratio of sine of angle of incidence to the sine of angle of refraction is a constant for the light of a given colour and for the given pair of media friend this is also known as snell's law of refraction.

when one constant is air or vacuum,this constant is called (Absolute refractive index).

more answer is in attachment .



nice to help u.

Answer 2

⭐⭐⭐Answer⭐⭐⭐

The second law of refraction is also known as Snell's law of refraction and it states that the ratio of Sine of the angle of incidence to the sine of refraction is constant for a given pair of media. It establishes a relation between angle of incidence and angle of refraction

Now, we know that sin i / sin r is constant.

Substituting the values, we will get the answer.
