A proton emits a gamma-ray photon with energy 2.0 MeV in a quantum jump from n =2 to n= 1.
The length of the box is:

What is the length of a one-dimensional box in which an electron in the state has the same energy as a photon with a wavelength of ?
The diameter of the nucleus is about . A simple model of the nucleus is that protons and neutrons are confined within a one-dimensional box of length . What are the first three energy levels, in , for a proton in such a box?
A incandescent lightbulb emits about of visible light. (The other are emitted as infrared radiation or lost as heat to the surroundings.) The average wavelength of the visible light is about , so make the simplifying assumption that all the light has this wavelength. How many visible-light photons does the bulb emit per second?
Draw an energy-level diagram, similar to Figure 38.21, for the ion. On your diagram:
a. Show the first five energy levels. Label each with the values of n and
b. Show the ionization limit.
c. Show all possible emission transitions from the n = 4 energy level.
d. Calculate the wavelengths (in nm) for each of the transitions in part c and show them alongside the appropriate arrow.
Dinoflagellates are single-cell organisms that float in the world’s oceans. Many types are bioluminescent. When disturbed, a typical bioluminescent dinoflagellate emits 108 photons in a 0.10-s-long flash of wavelength 460 nm. What is the power of the flash?
