Question

calculate speed of light in water in rarefactive index 4/3​

Answer 1

Answer:

2.25×10^8m/s

Explanation:

Refractive Index of water  = Speed of light in vacuum / speed of light in water

4/3 = (3*10^8) / x

x = 2.25×10^8m/s

Answer 2

Answer:

refractive index= speed of light in vaccum

speed of light in medium

→ 4/3 = 3 × 10^8

v

→ v = 2.25 × 10^8 m/s
