Question

Refractive index of diamond wrt glass is 1.6 and absolute refractive index of glass is 1.5. find out the absolute refractive index of diamond.

Answer 1

Refractive index = Speed of light in one medium / Speed of light in other medium.

Absolute refractive index means refractive index with respect to air.

So, for glass,1.5 = Speed in air / Speed in glass
1.5 = 300000000/Speed in glass.
Speed in glass = 300000000/1.5
Speed in glass = 200000000

Similarly,
1.6 = Speed in glass / Speed in diamond.
1.6 = 200000000/Speed in diamond
Speed in diamond = 200000000/1.6
Speed in diamond = 125000000

Refractive index of diamond = Speed In air/ Speed in diamond.
Refractive index = 300000000/125000000
Absolute Refractive index of diamond = 2.4

Answer 2

Answer:

2.4

Explanation:

because we should do 1.5*1.6
