Question

light passes from air into an unknown material at an angle of incidence of 43° and an angle of refraction of 28°. what is the index of refraction of the unknown material ?Light passes from air into an unknown material at an angle of incidence of 43° and an angle of refraction of 28°. what is the index of refraction of the unknown material ?

Answer 1

Answer:

1.45

Explanation:

first the formula to find the refractive index of a material is = sin i/sin r

where i is the angle of incidence

and r is the angle of refraction

so we have sin 43/sin 28 = 1.45

as sinple as that
