Question

calculate the refractive index if the thickness of glass slab is 7 cm with vertical shift of 4 cm​

Answer 1

Answer:

7/4=1.75 therefore the answer is 1.75

Answer 2

Given:

The thickness of the slab is= 7 cm

The vertical shift is = 4 cm

To find:

The refractive index of the glass slab.

Solution:

The relationship between the thickness of glass slab, refractive index of glass slab and its vertical shift is:

$\delta = t( \mu - 1)$

On substituting the values in the equation, we get:

$4 = 7( \mu - 1)$

$\frac{4}{7} = \mu - 1$

$0.57 = \mu - 1$

$\mu = 1.57$

Thus, the value of refractive index of the glass slab is 1.57.
