Question

What is the speed of light in a medium having refractive index 2 ?​

Answer 1

Answer:

If the speed of light in a vacuum is c, and the speed of light in the medium is v < c, then the refractive index of the medium is c/v.

It is usually acceptable to express speed in terms of the speed of light.

v = c/n

So, for n = 2, v = “half lightspeed” = 0.5c

Just do 1/n and write “c” after it.

Answer 2

Answer:

The index of refraction is equal to the speed of light in a medium divided by the speed of light in a vacuum. We can find the time to travel a given distance by manipulating this equation and combining it with the equation for rate. Plug in the given values and solve for the velocity in the medium.
