State the Snell’s laws of refraction of light.
नियम
उत्तर
Second law of refraction, i.e. `(sin i)/(sin r)` = 1μ2 or 1n2 is called Snell's Law.
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for a pair of given media.
μ = `sin i/sin r`
Snell's Law
`n_1/n_2 = sinθ_2/sinθ_1`
