Question

Speed of light is minimum in??​

Answer 1

the velocity of light is maximum in vacuum I.e 3*10^8 m/s. as the density of the medium increases the velocity of light decreases in the medium. so the velocity of light is less in watt than in atmosphere. the thicker the medium is the slower the electromagnetic wave, so the velocity of light will be minimum in the thickest medium.

Hope it helps you, hv a nyc day

Answer:

speed of light in vaccum is

$3\times {10}^{8}$

I don't know in minimum
