You have a new summer job with NASA and are working on astronomical observations using electromagnetic radiation that is not in the visible range. Your supervisor has explained 21cm radiation….
Identify the region of the electromagnetic spectrum to which this wavelength belongs.
In Problem 14, we find that the particle in a box is not a good model for the electron in a hydrogen atom. As it turns out, the particle in a box is a reasonable first approximation for a model for the protons in the nucleus. Work with your group to show this as follows. Imagine a proton confined in an infinitely high square well of length 10.0 fm, a typical nuclear diameter. Assuming the proton makes a transition from the n = 2 state to the ground state, calculate (a) the energy and (b) the wavelength of the emitted photon. (c) Identify the region of the electromagnetic spectrum to which this wavelength belongs.
