An electron confined to a one-dimensional box has a ground-state energy of 35.0 eV. If the box were somehow made twice as long, how would the photon's energy change for the same transition (first excited state to ground state)? o O increase the energy to three times as much as before o reduce the energy to one third as much as before o reduce the energy to one fourth as much as before o ) reduce the energy to one...

The particle in a box model is often used to make rough estimates of energy level spacings. For a metal wire 10.0 cm long, treat a conduction electron as a particle confined to a one-dimensional box of length 10.0 cm. Which of the following shows the wave function was a function of position for the electron in this box for the ground state? We were unable to transcribe this image
Assume that four electrons are confined to a one dimensional box 4.95 ✕ 10−10 m in length. If two electrons can occupy each allowed energy level, calculate the wavelength of electromagnetic radiation necessary to promote the highest-energy electron into the first excited state.
5. The energy levels of an electron in an atomic-like system are given by the expression E- -Cn' C> O, p>O n 1,2,3,... If the ionization energy for the electron in its ground state is 20 eV, and a photon of wavelengthl00 nm is emitted when the electron makes a transition from the third level to the ground state, find Cand p.
An electron confined to a box absorbs a photon with wavelength λ. As a result, the electron makes a transition from the n = 1 state to the n = 3 state. (a) Find the length of the box. (Use the following as necessary: c, h, me, and λ.) L = (b) What is the wavelength λ' of the photon emitted when the electron makes a transition from the n = 4 state to the n = 2 state? (Give...

Energy (eV) 1. The figure to the right shows the first few energy levels for lithium. The ground state for the valence electron (the electron most likely to change 4 energy levels) is the 2s state which is why that state is set to O eV. Make a table showing all possible transitions in the emission spectrum. For each possible transition indicate A. Energy change of possible transition. B. At for the transition. Is the transition allowed? C. Wavelength of...
