Question

refractive index of water is 1.33
speed of light in water will be:
a. 1.33 x 108m/s
b. 3 x 108m/s
c. 2.26 x 108m/s
d. 2.66 x 108m/s
pls provide the explanation also

​

Answer 1

Answer:

Refractive index = Speed of light in vaccum / Speed of light in water. It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s.

Therefore, refractive index of the water can be measure by the Speed

Hope it helps you

Thanks....
