Question

state snells law of refraction .
tell the details till 10 standard

Answer 1

sin I/sinr=constant

that's my answer

Answer 2

According to Snell’s law of refraction, the ratio of sine of angle of incidence (z) in the first medium to the sine of angle of refraction (r) in the second medium is constant called the refractive index (n).

Mathematically n = sin i /sin r
