Question

If the refractive index of ice is 1.31. What will be speed of light in ice

Answer 1

Answer:

2.29×10^8 m/s

Explanation:

Refractive index of a medium =1.31

Speed of light in ice = ?

It is given that the refractive index of water is 1.33.

The speed of light in vacuum is 3\times 10^8 m/s.

So,

Speed of light in vacuum = 3×10^8 m/s

Then,

Speed of Light in ice = 3×10^8/1.31

2.29×10^8 m/s

Answer 2

Answer:

2.29×10^8 m/s

Explanation:

3×10^8 /1.31
