A student of 65 kg has grown concerned about being diffracted if passing via a 90 cm broad doorway.
(i) When the student is traveling at a whopping 0.5 m/s, determine the momentum of student?
(ii) Determine the de Broglie wavelength of the student?
(iii) Determine what would the size of the door require to be in order for there to be perceptible diffraction of the student?
