Another way of looking at the fact that all objects have wave-like properties is diffraction. Waves diffract as they move through a small opening and technically quantum mechanics means that all objects should diffract like a wave when going through a "slit". Again, let's assume the object is our 62 kg physics student and she moves through the "slit" of a 0.79 m wide door. We know that the diffraction of a wave first becomes significant when the width of the aperture is comparable to the wavelength of the waves being diffracted.
At what speed should the student be moving in order to have signficant diffraction as she enters the door?
