The refractive index of glass with respect to water is 9/8. If the velocity and wavelength of light in water are 2.25×108 m/s and 5400 A0 respectively find the velocity and wavelength of light in glass

μgμw=98;μ∝1V,μgμw=VwVg;μgμw=λwλg⇒Vg=Vw×μwμg=2.0×108 m/s⇒λg=λw×μwμg=4800 A0

Detailed Solution

$\frac{μ_{g}}{μ_{w}} = \frac{9}{8}; μ \propto \frac{1}{V}, \frac{μ_{g}}{μ_{w}} = \frac{V_{w}}{V_{g}}; \frac{μ_{g}}{μ_{w}} = \frac{λ_{w}}{λ_{g}}$

$\Rightarrow V_{g} = V_{w} \times \frac{μ_{w}}{μ_{g}} = 2.0 \times 10^{8} m / s$

$\Rightarrow λ_{g} = λ_{w} \times \frac{μ_{w}}{μ_{g}} = 4800 \overset{0}{A}$
