Answers

Answered by shivanshshrivastava7

Explanation:

He discovered that the speed of light in water or glass was only about two-thirds of the value in air, and he also concluded that the speed of light through a given medium is inversely proportional to the refractive index.

Answered by subha2007293

Answer:

For example, for visible light, the refractive index of glass is typically around 1.5, meaning that light in glass travels at c / 1.5 ≈ 200000 km/s (124000 mi/s); the refractive index of air for visible light is about 1.0003, so the speed of light in air is about 90 km/s (56 mi/s) slower than c.

One light year: 1.0 year

Miles per second: 186000

The length of Earth's equator: 134 ms

From Moon to Earth: 1.3 s
