Calculate the time taken by light to travel a distance of `10 km` in water of refractive index `4//3`.

The time taken by the light to travel a distance of 3 cm is :

The time taken by a monochromatic light to travel a certain distance in air in 9 xx 10^(-6) seconds. The time taken by the light ray to travel the same distance in water of refractive index (4)/(3) is

The time taken by a monochromatic light to travel a certain distance in air in 9 xx 10^(-6) seconds. The time taken by the light ray to travel the same distance in water of refractive index (4)/(3) is

If c is the velocity of light in free space, then the time taken by light to travel a distance x in a medium refractive index mu is

If c is the velocity of light in free space, then the time taken by light to travel a distance x in a medium refractive index mu is

If c is the velocity of light in free space, the time taken by light to travel a distance x in a medium refractive index mu is

If c is the velocity of light in free space, the time taken by light to travel a distance x in a medium refractive index mu is

If c is velocity of light in free space, the time taken by the light to travel a distance x in a medium of refractive index mu is given by

Velocity of light in air is 3 xx 10^8 m//s and refractive index of water is 1.33. The time taken by light to travel a distance of 500 m in water is
