# Reflection of light and snail law

A ray of light runs through a straight line, but when the ray of light

goes through a transparent medium to another transparent medium,

then it gets distracted by its path. In the second medium, the beam,

either towards the first medium, either bends towards the

perpendicular or away from the perpendicular

If the light beam goes from one medium to another, it is called

"refraction" from its path, if the refracted ray bends toward

the relation relative to the incident ray, then the second is called

the dense relative to the medium, but if the refracted ray is an

incident ray Removed from the relative angle, then the other

medium is called the relative viral of the first

Light refraction has two rules
1 Incident ray, refracted ray and perpendicular to the point of

view are all in the same plane

2 For any two of the medium and for the light of certain colors

(wavelength), the ratio of sin to the angle of incidence and the

angle of refraction remains constant.

If the angle of incidence is i and the angle of refraction then

$\frac{sin&space;I}{sin&space;R}=costant$

This rule is called the snail rule. This determinant is called the

refractive index of the second medium relative to the first medium

, if we first display the medium 1 and the second medium 2, the

refractive index is displayed from 1N2.
