    A cricket ball of 0.5 kg is moving with a velocity of 100 m/sec. The wavelength associated with its motion is:

    A)  1/100 cm      

    B)  \[6.6\times {{10}^{-34}}m\]

    C)  \[1.32\times {{10}^{-35}}m\]  

    D) \[6.6\times {{10}^{-28}}m\]

    Correct Answer: C

    Solution :

     From de Broglie equation: \[\lambda =\frac{h}{m\upsilon }\] \[=\frac{6.62\times {{10}^{-34}}}{0.5\times 100}\] \[=1.32\times {{10}^{-35}}m\]
