Question

Refractive index of water is 1.3. calculate the speed of light in water.​

Answer 1

The speed of light is faster in water. The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.

Answer 2

`2.31*10^(8) m/s`

Step-by-step explanation:

Employ the formula attached below,

n = c/v

1.3 = (3.0*10^8)/ x

(solve for x)

x= (3.0*10^8) / 1.3

x=
`2.31*10^(8) m/s`
