Vedclass · Answer

(C) The refractive index $\mu$ of a medium is defined as the ratio of the speed of light in vacuum (or air) $c$ to the speed of light in that medium $v$.Formula: $\mu = \frac{c}{v}$Given:Speed of light in air,$c = 3 	imes 10^8 \, m/s$Refractive index of diamond,$\mu = 2.4$Rearranging the formula to find the speed in diamond $(v)$:$v = \frac{c}{\mu}$$v = \frac{3 	imes 10^8}{2.4}$$v = 1.25 	imes 10^8 \, m/s$Therefore,the speed of light in diamond is $1.25 	imes 10^8 \, m/s$.

The speed of light in air is $3 \times 10^8 \, m/s$. What will be its speed in diamond,whose refractive index is $2.4$?
