Question

Define refractive inden of water. If the
speed of light in air 3x108 b/s and the
Speed of light in air is 3 x 18 m/s and
speed of light in water is 22 x 18 m/s
the​

Answer 1

Answer:

Explanation:Speed of light in vacuum = 3.0×108m/s

Speed of light in water = 2.25×108m/s

Refractive index of water = ?

We know that

Refractive index of water = Speed of light in water Speed of light in vacuum​

Refractive index of water = 2.25×1083×108​=1.33
