On average, people in Adelaide have a mass of m=85.5kg and walk at a speed of v=2.12ms−1. If we were to consider such a person to be a particle with mass mm and speed vv, then they would have a de Broglie wavelength of λ≈3.66×10−36m when walking. Explain why the average Adelaidean is not observed to diffract when walking through a doorway
Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
