JEE Main & Advanced Chemistry Structure of Atom Question Bank Uncertainty principle and Schrodinger wave equation

  • question_answer According to heisenberg uncertainty principle [AMU 1990; BCECE 2005]

    A)                 \[E=m{{c}^{2}}\]              

    B)                 \[\Delta x\times \Delta p\ge \frac{h}{4\pi }\]

    C)                 \[\lambda =\frac{h}{p}\]             

    D)                 \[\Delta x\times \Delta p=\frac{h}{6\pi }\]

    Correct Answer: B

    Solution :

     According to uncertainty principle, the product of uncertainties of the position and momentum, is \[\Delta x\times \Delta p\ge h/4\pi \].
