Vedclass · Answer

(B) The refractive index $\mu$ of a medium is inversely proportional to the speed of light $v$ in that medium,given by $\mu = c/v$,where $c$ is the speed of light in a vacuum.Therefore,$\mu \propto 1/v$,which implies $\mu_g v_g = \mu_w v_w$.Given: $\mu_g = 3/2$,$\mu_w = 4/3$,and $v_g = 2.00 	imes 10^8 \ m/s$.Using the relation $\frac{\mu_g}{\mu_w} = \frac{v_w}{v_g}$:$\frac{3/2}{4/3} = \frac{v_w}{2.00 	imes 10^8 \ m/s}$$\frac{9}{8} = \frac{v_w}{2.00 	imes 10^8 \ m/s}$$v_w = \frac{9}{8} 	imes 2.00 	imes 10^8 \ m/s = 2.25 	imes 10^8 \ m/s$.

The refractive index of glass is $3/2$ and the refractive index of water is $4/3$. If the speed of light in glass is $2.00 \times 10^8 \ m/s$,the speed of light in water will be:
