Question

When an electron trapped in a one-dimensional box transitions from its

n = 2

state to its

n = 1

state, a photon with a wavelength of 636.4 nm is emitted. What is the length of the box (in nm)?

What If? If electrons in the box also occupied the

n = 3

state, what other wavelengths of light (in nm) could possibly be emitted? Enter the shorter wavelength first.

shorter wavelength  nmlonger wavelength  nm
