Question

2 The refractive index of water is 1.33. the
Speed of light
in water
will be​

Answer 1

$\huge \purple {answer}$

Refractive index = Speed of light in vaccum / Speed of light in water. It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s. Therefore, refractive index of the water can be measure by the Speed of light in water is 2.25 × 10^8 m/s.
