Question

The refractive index of glass is more than the refractive index of
water. In which of these two media, light travels the fastest..?


pl tell fast

Answer 1

Answer:

Light travels Faster in air, but slower in glass.In different materials, the speed of light slows down to less than c. That is because light refracts when it encounters different mediums. ... The equation is n=c/v. In water, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water, than it travels through glass.
