Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water and 200,000 kilometers per second in glass (refractive index of 1.5).

ANSWER-:

The speed of light in vacuum is the highest. Air, and any other medium, will slow it down by a factor known as the “refractive index”…
