Answer 1

Heya mate
The answer is here



Question
Laws Of Refraction




Answer
Laws of Refraction:
1) The incident ray, refracted ray and normal to the interface of given two transparent media, all lie in same plane.
2) The ratio of sine of angle of incidence and sine of angle of refraction is always constant for the light of given colour and for the pair of given media.
The Second Law of Refraction is also known as Snell’s Law of Refraction.

Sin i / Sin r = Constant




hope it helps

Answer 2

Answer:

In 11th class refraction is not there .  

Law of refraction are :  

The incident ray , reflected ray and the normal at the point of incidence all lie in the same plane .  

The ratio must be constant of sine angle between incidence and reflected ray .  

Mathematically:  

sin i / sin r = k .  

One similar terms comes of ratio:  

Refractive index :  

It is ratio of speed of light in any given medium .

Mathematically :  

n =  velocity of light  medium 1  / velocity of light in medium 2
