    Number of waves in 8 cm of vacuum is same as number of waves in \[x\] cm of a medium. Refractive index of medium is 4/3, then the value \[x\] is

    A)  32/3 cm       

    B)  12cm

    C)  6 cm           

    D)  4 cm

    Correct Answer: C

    Solution :

    Refractive index of medium with respect to air       \[_{a}{{\mu }_{m}}=\frac{Distance\text{ }for\text{ }n\text{ }waves\text{ }in\text{ }air}{Distance\text{ }for\text{ }n\text{ }waves\text{ }in\text{ }medium}\]                 \[\frac{4}{3}=\frac{8}{x}\] \[x=6\,\,cm\]
