The Speed of Light is Maximum in which of the following Mediums? A) Air B) Glass C) Vacuum D) Water

Maximum Speed of Light in Which Medium

The speed of light is always the fastest in a vacuum, followed by air. No intermediary is needed for the light to go from one place to another. The fact that a vacuum is a completely obstruction-free medium for the movement of light results in a vacuum moving faster than air, which raises the refractive index of air. The symbol for it is c. Following the speed of light is this order:-

Vacuum> Air> Water> Glass

As the Vacuum is the clearer medium for the light to travel without any hindrances, the speed of light is the most in Vacuum.

• The velocity of light in a rarer medium is greater than its velocity in any denser medium.
• No object can move faster than the speed of light, claims the special theory of relativity.
• The distance is also calculated using the speed of light.
• When we say a star is one light-year distant, we mean it will take one year for light to travel there.
