↪️ Second law of refraction states that for two given media, the ratio sinisinr=constant s i n i s i n r = c o n s t a n t , where i is the angle of incidence and r is the angle of refraction. Refractive index (n) of a medium is given by n=sinisinr.

Answer 2

Answer:

Explanation:

also called Snells law

states that for a pair of media ,sini/sinr=constant which is =n2/n1

i- angle of incidence

r - angle of refraction

n2 - refractive index of 2 nd medium

n1  refractive index of 1 st medium
