Question

what is the speed of light in medium of refractive index 1.4 if it's speed in air is 3​

Answer 1

Answer:

Q:What is the speed of light in a medium of refractive index 6/5 if its speed in air is 3,00,000 km/s?

Explanation:

Refractive index of medium = 6/5 = 1.2

Speed of light in air = 3,00,000km/s

We know that

Refractive index of the medium = speed of light in air/speed of light in medium

1.2 = 300000/speed of light in medium

Speed of light in medium = 250000km/s
