Question

☺heya ❗❗❗
♦The refractive index of glass to water is 1/3 . find the critical angle ?
♦When light ray travel water to air if its critical angle is 45° . then find the refractive index to water to air ?
❗❗❗❗plz solve it guys ❗❗❗❗❗☺

Answer 1

see the pic for ur ans
for the first ans
we take angle of refraction is 90° as we know that critical angle is the angle of incidence of the denser medium corresponding to which the angle of refraction is 90°

Answer 2

Answer:

Explanation:

hey here is your answer...........

when a body covers equal distances in equal interval of time then it is said uniform motion

when a body cover unequal distances in equal interval of time then it is said to be non uniform motion.
