Question

thickness of transparent slab is 12 cm.A point object when placed at the bottom of the slab appears raised by 4cm.What is the refractive index of the slab​

Answer 1

Answer:

Refractive Index= 3/2

Explanation:

The Apparent depth of any object viewed through a glass slab is- thickness.

Refractive index

Therefore, since apparent depth is measured from the interface of the 2 different media, apparent depth is equal to 8cm.
