Question

3. The refractive index of water is 1.33. The speed of

light in water will be

(a) 1.33 x 108 m/s

(c) 2.26 x 108 m/s

(b) 3 x 108 m/s (d) 2.66 x 108 m/s​

Answer 1

Answer:

option c

see the picture .........

Answer 2

Step-by-step explanation:

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.
