Question

The refractive index of water is 133 and the speed of light in air is 3 108 ms1. Calculate the speed of light in water.

Answer 1

Hi Sahil,

as u know refractive index= speed of light in air/ speed of light in medium.

as given in the question 1.33=3×10^8/x

x=3×10^8/1.33

Hope so u understood.

Thanks. spread smile
