Question

The refractive index of water is 1.33
and the speed of light in air is
3 x 108ms-7. Calculate the speed of
light in water. ​

Answer 1

Answer:

Refrective index = speed

of ligth in vaccum / speed

of ligth in water. it is

denotes as n = c /v, v= c/

n = 3× 10^ 8m/s / (1.33 ) =

2.25 ×10^8 m/s.

Explanation:

therefore, refrective index of tge water can be measure by the speed of ligth in water is 2.25 × 10^8 m/s.
