    If \[{{V}_{g}},\,{{V}_{s}}\] and \[\,{{V}_{m}}\] are the speeds of gamma rays, X-rays and microwaves respectively in vacuum then:

    A)  \[{{V}_{g}}>{{V}_{m}}>{{V}_{s}}\]

    B)  \[{{V}_{g}}>{{V}_{s}}>{{V}_{m}}\]

    C)  \[{{V}_{g}}={{V}_{s}}={{V}_{m}}\]      

    D)  none of these

    Correct Answer: C

    Solution :

    Electromagnetic radiation is a propagating wave in space with electric and magnetic component. Gamma rays, x-rays and microwaves respectively are electromagnetic waves. They travel with the speed of light,                               Hence,       \[{{V}_{g}}={{V}_{x}}={{V}_{m}}\]
