Question

find the refractive index of a glass slab placed in air if the thickness of a slab is 3 cm and vertical shift is calculated as 1cm​

Answer 1

Apply formula

Normal/vertical shift = d (1-1/μ)

d = actual depth(thickness)

by substituting the given values we get as

1 = 3(1-1/μ)

1 = 3 -3/μ

3/μ = 2

μ = 1.5
