Question

the speed of light is 2*10^5 km/s what is the refractive index of glass

Answer 1

hey mate ,,,

^_^here's ur answer,,,


we define,

RD= speed of light in vaccum/speed of light in given material..

R.D = 3×10^8m/s/2×10^8= 3/2= 1.5


therefore the refractive index of glass is 1.5,,
no unit ,, and it is dimensionless quantity,,,

sorry for late,,,

^_^^_^. hope it helps u(^_-)(^_-)

Hey there!

QUESTION
-------------------
The speed of light is 2*10^5 km/s. What is the refractive index of glass?

SOLUTION
-----------------
Given,

Speed Of Light = 2 × 10^5 km/s

Refractive index of glass = ?

We have,

Refractive index of glass =

Speed of light in vaccum
--------------------------------------
Speed of light in glass

3 × 10^8 m/s
--------------------
2 × 10^8 km/s

=> 1.5

Hence, The refractive index of glass is 1.5

Hope It Helps!
