Answer:
snells law says that sin i/sin r =ú
or the ratio of sin of incidence of is to sin of refraction is equal to refractive index of that substance frthrough which light is propogating

The snell's law states that the ratio of sine of angle of incidence to the sine of angle of refraction is always constant for two reasons. →μ(constant) = refractive index = sinisinr.
The formula of snells law is
A beam of light in air makes an angle of 41.8° relative to the normal to the surface of a pool of clear water. The index of refraction for air is 1.000, and the index of refraction for the water is 1.333.
