Question

The speed of light in air is Va, whereas that of the speed of light in water is
Vw. What is the refractive index of water with respect to air?
A) 1
B) 0.75
C) 1.32
D) 2.64

Answer 1

Answer:

Explanation:

the answer is option B that is 0.75 because it is said that with respect to air hence 10^8 get cancelled and remain 2.26/3

3 because the speed of light is 3x 10^8 m/s

hence after dividing the value we get is 0.75333333333

which means 0.75

hope its right and thanks for my answer
