Question

refractive index of water is 1.33 and speed of light in air is 3*10^8calculate the speed of light in water​

Answer 1

Refractive index of water = c / v

= 1.33 = 3 × 10^8 / v

= v = 3 × 10^8 / 1.33

= v = 2.25 m / s

Answer 2

Answer:

v=2.25m/s

Explanation:

refractive index= 1.33

speed of light = 3*10^8

refractive index = c/v

1.33=3*10^8/v

v=3*10^8/1.33

v=2.25m/s
