Given:

Wavelength of light \lambda = 5890 \times10^{-10} m

Speed of light c = 3 \times 10^{8} \frac{m}{s}

Refractive index n = 1.6

To Find:

Wavelength of light in glass,

From the formula of wavelength of light in medium,

    n = \frac{\lambda }{\lambda _{mid} }

\lambda _{mid} = \frac{\lambda }{n}

\lambda _{mid} = \frac{5890 \times 10^{-10} }{1.6}

\lambda _{mid} = 3681 \times 10^{-10} m

Therefore, the wavelength of light in glass is 3681 \times 10^{-10} m
