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