Question

Refractive index of glass=1.5,refractive index of water=1.33; what will be the velocity of light in water if in glass medium it is 2×10^8m/s​

Answer 1

Answer:

Refractive index of glass=1.5

velocity of light in glass medium=2×10⁸m/s

refractive index of water=1.33

refractive index formula=velocity of light in air medium/velocity of light in the medium

therefore velocity of light in water medium=3×10⁸/1.33=2.3×10⁸m/s
