In a vacuum the speed of light is 300000000 m/s. If light slows down to 200000000 m/s in glass, calculate the refractive index of
glass. Urgent pls hurry

n = 1.5

Explanation:

The speed of light in vacuum is 300000000 m/s

The speed of light in glass is 200000000 m/s

We need to find the refractive index of the glass.

We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.

So, the refractive index of the glass is 1.5.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
