Question

The diffraction phenomenon can be observed whenever the wavelength is comparable in magnitude to the size of the slit opening. To be “diffracted,” how fast must a person weighing 84 kg move through a door 1 m wide

    Answer:

    Velocity,v=7.89\times10^{-36}m/s

    Explanation:

    Diffraction will only occur when the wavelength,\lambda, is comparable in size to the slit opening. Given the,\lambda=1m,,and mass of the person as 84kg, we can apply

    De-Broglie equation, to obtain the velocity.

    \lambda=\frac{h}{mv}\\v=\frac{6.626\times10^{-34}Js}{84kg\times1m}\\v=7.89\times10^{-36}m/s

    The velocity of the person is 7.89\times10^{-36}m/s
