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

    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 \[\lambda =\frac{h}{mv}\] \[=\frac{6.62\times {{10}^{-34}}}{6.62\times {{10}^{-29}}\times {{10}^{-3}}\times {{10}^{3}}}\] \[={{10}^{-5}}\,m\]
