An electron is contained in a one-dimensional box of length 0.520 nm.(a) Draw an energy-level diagram for the electron for levels up to n = 4.
(b) Photons are emitted by the electron making downward transitions that could eventually carry it from the n = 4 state to the n = 1 state. Find the wavelengths of all such photons (in nm).
Please help!
When an electron in a one-dimensional box makes a transition from the n = 1 energy level to the n = 2 level, it absorbs a photon of wavelength 426 nm. What is the wavelength of that photon when the electron undergoes a transition (a) from the n = 2 to the n = 3 energy level and (b) from the n = 1 to the n = 3 energy level? (c) What is the width L of the box?
An electron is trapped in a
one-dimensional box that is 501 nm wide. Initially, it is in the n = 3 energy level but, after a photon
is absorbed, the electron is in the n = 6 energy level. What was the wavelength of the absorbed photon?
wavelength:
.0306
Eventually, the electron ends up in the ground state. As it does so, one or more photons are emitted during those transitions.

to the ground state.
