14. what is the speed of light in a medium of refractive index if its speed in air is 3,00,000 km/s?

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?

Medium refractive index = 6/5 = 1.2

In the air, the speed of light is 3,00,000 km/s.

We know that the medium’s refractive index = (light speed in air)/ (speed of light in medium)

(300000)/1.2 = (speed of light in medium)

Light travels at a speed of 2500000 km/s through the medium.

Given:Speed of light in air = 3,00,000 km/sRefractive index of the medium = 6/5Speed of light in the given medium = ?Applying formula for refractive index, we get:Refractive index of a medium = (Speed of light in air) / (Speed of light in medium)or(Speed of light in medium) = (Speed of light in air) / (Refractive index of a medium)= 3,00,000 / (6/5)

= 2,50,000 km/s

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 ?
