Diffraction effects become significant when the width of an aperture is comparable to the wavelength of the waves being diffracted. (a) at what speed will the de broglie wavelength of a 65-kg student be equal to the 0.76-m width of a doorway? (b) at this speed, how much time will it take the student to travel a distance of 1.0 mm? (for comparison, the age of the universe is approximately 4 * 1017 s.)
