    What is the wavelength (in m) of a particle of mass \[6.62\times {{10}^{-29}}g\]moving with a velocity of \[{{10}^{3}}\text{ }m{{s}^{-1}}\] ?

    A)  \[6.62\times {{10}^{-4}}\]     

    B)  \[6.62\times {{10}^{-3}}\]

    C)  \[{{10}^{-5}}\]

    D)  \[{{10}^{5}}\]

    Correct Answer: C

    Solution :

    According to de-Broglie equation \[\lambda =\frac{h}{mv}\] \[=\frac{6.62\times {{10}^{-34}}}{6.62\times {{10}^{-29}}\times {{10}^{-3}}\times {{10}^{3}}}\] \[={{10}^{-5}}m\]
