To determine refractive index of glass slab using a travelling microscope, minimum number of readings required are :

Accepted Answer

The refractive index is

$μ = \frac{Real d e p t h}{A p p a r e n t d e p t h} = \frac{Reading 3 - R e a d i n g 1}{Reading 3 - R e a d i n g 2}$

Therefore, the minimum of three readings are required.
