Question

Refractive index of Glass is 1.5 what does this statement means

Answer 1

Refractive index of glass is 1.5 .This means that the speed of light in glass is 1.5 times slower than the speed of light in vacuum..
Hope it helps!!

Answer 2

Answer:

It means that the speed of light in it is 1.5 times slower than in a vacuum

Explanation:

A material's refractive index is computed as follows:

$\mu=\frac{c}{v}$         (1)

Where,

μ=refractive index of a material

c=speed of light in a vacuum=3×10⁸m/s

v=speed of light in a medium

Glass has a refractive index of 1.5, which implies that the speed of light in it is 1.5 times slower than in a vacuum. This can be demonstrated using an equation (1).

Equation (1) yields the following result when the value of =1.5 is substituted:

$1.5=\frac{c}{v}$

$v=\frac{c}{1.5}$

Hence, proved.
