Question

the refractive index of water is a 4/3 and the speed of the light in air is 3×10^8 m/s. find the speed of the light in water ?​

Answer 1

Answer:

Answer is 2.25×10⁸ m/s

Explanation:

refractive index of water with respect to air is= 4/3

speed of light in air = 3×10⁸ m/s

so,

speed of light in air =4/3

speed of light in water

3×10⁸ = 4/3

speed of light in water

speed of light in water = 9×10⁸ m/s

4

= 2.25 ×10⁸ m/s
