Question

Answer 100% correct otherwise don't answer the refractive index of water is 1.33 and the refractive index of diamond is 2.52 calculate the speed of light in water and diamond​

Answer 1

Explanation

[n = refractive index,c = speed of light in vaccum,v = speed of light in a medium ]

1) Water

n = c/v

1.33 = 3 × 10^8 /v

v = 3 × 10^8 /1.33

v = 2.25 × 10^8 m/s

2) Diamond

n = c/v

2.52 = 3 × 10^8/v

v = 3 × 10^8/2.52

v = 1.19 × 10^8 m/s
