Question

Question 4:
If the absolute refractive index of water is
then find the speed of light in water ?​

Answer 1

Answer:

refractive index=speed of water\speed of light,

Answer 2

Answer:

water π air=speed of light in air/ speed of light in water

=>4/3=3*10^8/v

=>v=3*10^8/4/3=9*10^8/4=2.26*10^8...
