Question

The absolute refractive index of ruby is 1.7 find the speed of light in ruby the speed of light in vacuum is 3 into 10 to the power 8 metre per second

Answer 1

Answer:

we know that,

1. velocity of light in a medium (V) = speed of light in vacuum(C) /refractive index of the medium
2. here,
3. v=3*10^8/1.7
4. v=1.76*10^8
