Question

why speed of light is maximum in vacuum​

Answer 1

Not truly a constant, but rather the maximum speed in a vacuum, the speed of light, which is almost 300,000 kilometers per second, can be manipulated by changing media or with quantum interference.

I hope it will be helpful to you friend,

Please thank my answer………

Answer 2

Answer:

Not truly a constant, but rather the maximum speed in a vacuum, the speed of light, which is almost 300,000 kilometers per second, can be manipulated by changing media or with quantum interference.Yes light travels faster in vacuum than any other medium. This is because there is no obstruction in vacuum for the propagation of light and thus, the refractive index of vacuum is the lowest. Show the speed of light in vacuum is the maximum
