Consider a singly charged Helium nucleus (He+). Argue that the Bohr model will work in describing spectroscopic emissions from this system. Now compute the frequency, wavelength and momentum of light emitted as the electron jumps from the n=5 to n=4 level. Do this by using the electron mass as well as the reduced mass. Why should the reduced mass give better results? Compute the percentage difference between the two. Using the Heisenberg Uncertainty relationship (ΔxΔp≥ℏ/2), estimate the radius of He+ for the n=5 level. You may assume the uncertainty in energy to be the same order as the energy of this level.
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.
