Question

. Speed of light in air is 3.0 x 10 m/s. If refractive
3
index of water is then find speed of light in
2
water



​

Answer 1

Answer:

speed of light in water = 4.5 x 10 m/s

Answer 2

Answer:

$Speed \: \: of \: \: light \: \: in \: \: water=2.25 \times {10}^{8}m \: per \: sec$

Refractive index of water is 1.3 or 5/3
