Question

Find the refractive index of glass slab if its thickness is 6 cm and vertical shift is 2 cm

Answer 1

Answer:

ans is 2/3

Explanation:

as glass slab is 6cm hence we conclude real depth is 6cm and apparent depth is real depth minus shift

formula :

u1/u2=real depth/apparent depth

as u1=1 for refaractive index of air is 1

by substituting values you'll get your answer

Answer 2

Given that,

The thickness of the glass slab is 6 cm, and the vertical shift is 2 cm.

So, the real depth of the glass slab is 6 cm.

Now,

We need to find the refractive index of the glass slab.

Answer :-

We know that, real depth = apparent depth - vertical shift.

⇒6 = apparent depth - 2

⇒Apparent depth = 6 + 2

⇒Apparent depth = 8

Now, Refractive Index (R.I) = Real depth/Apparent depth

⇒R.I = 6/8

⇒R.I = 3/4
