Vedclass · Answer

(D) The refractive index $\mu$ is inversely proportional to the speed of light $v$ in a medium,given by $\mu = \frac{c}{v}$,where $c$ is the speed of light in vacuum.Therefore,$\mu_g v_g = \mu_w v_w$.Given: $\mu_g = 1.5$,$\mu_w = 1.3$,and $v_w = 2.25 	imes 10^8 \, m/s$.Substituting the values: $1.5 	imes v_g = 1.3 	imes 2.25 	imes 10^8$.$v_g = \frac{1.3 	imes 2.25 	imes 10^8}{1.5}$.$v_g = 1.3 	imes 1.5 	imes 10^8$.$v_g = 1.95 	imes 10^8 \, m/s$.

The refractive index of glass is $1.5$ and that of water is $1.3$. If the speed of light in water is $2.25 \times 10^8 \, m/s$,what is the speed of light in glass?
