Question

law of refraction and law of snell is same explain in please

Answer 1

snell's law is the second law of refraction..........
in which the sine angle of incidence upon sine angle of refraction is equal to a constant................

Answer 2

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used todescribe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
