    Monochromatic light is refracted from air into the glass of refractive index\[\mu \]. The ratio of the wavelength of incident and refracted waves is:

    A) 1:1        

    B) \[\mu :1\]                         

    C)  1:\[{{\mu }^{2}}\]         

    D) \[1  :\mu \]

    Correct Answer: B

    Solution :

    Since, from the formula \[\lambda =\frac{c}{v}\] hence, \[\frac{{{\lambda }_{a}}}{{{\lambda }_{g}}}=\frac{{{c}_{a}}}{{{c}_{g}}}=\mu =\mu :1.\]
