Question

"The refractive index of water is 1.33" . Explain this statement

Answer 1

speed of light in water with respect to air is know as refractive index of water and its value is 1.33

Answer 2

Answer:

It mean that:-

1)The water refracts/bend light 33% more as compared to vacuum/air

2)The velocity of light in water is decrease by 33% when it enter from air to vacuum.
