The light travels a distance of 500 m in water . It is given that `mu` for water is `(4)/(3)` and the velocity of light in vacuum is `3 xx 10^(10)` cm/s . What is the equivalent optical path ?

A

566.66 m

B

666.66 m

C

586 .45 m

D

576.66 m

Text Solution

Verified by Experts

The correct Answer is:
B
Optical path
`= mu xx ` distance travelled in the medium (water)
`= (4)/(3) xx 500 = (2000)/(3) = 666.66` m
