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 * 10^17 s.)
When an aperture's diameter matches the wavelength of the waves being diffracted, the effects of diffraction become noticeable. (A) At what speed would a 75-kg student's de Broglie wavelength be the same as a doorway's 0.76-m width? (b) How long will it take the student to traverse 5.0 millimeters at current speed? (In contrast, the universe is thought to have existed for about 4 * 1017 seconds.)
Assuming that the smallest measurable wavelength in an experiment is 0.990 fm (femtometers), what is the maximum mass of an object traveling at 269 m/s for which the de-Broglie wavelength is observable?
