Alightbulb produces electromagnetic waves with an average power of 2.5 w. (3396) problem 3: ㅿ what is the magnitude of the electric field (in v m) of these electromagnetic waves a distance of 4.5 m away from the bulb? for simplicity, reat the lightbulb as a point particle for the source of the electromagnetic waves and that the electromagnetic waves are propagating in vacuum

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?
