Select all of the following statements that are correct. The only difference between microwaves and ultraviolet light is their frequency (or wavelength). Microwaves have a shorter wavelength than visible light waves. Blue light is generally higher in energy than red light. X-Rays travel faster than radio waves when in the same medium.

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
