Question

Light travels from
(an angle of
medium of refractive index 1.6 at
incidence 30° into another medium
,
making an
of refraction us. Find the refractive index of second medium?​

Answer 1

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. As per Snell's law and the given information,

n

1

sin i = n

2

sin r

∴

sin r

sin i

=

n

1

n

2
