.8 O An electron is trapped in a one-dimensional infinite well
and is in its first excited state. Figure 39-27 indicates the five longest
wavelengths of light that the electron could absorb in transitions
from this initial state via a single photon absorption: A, = 80.78 nm,
A, = 33.66 nm, A = 19.23 nm, A, = 12.62 nm, and A, = 8.98 nm.

Figure 39-27 Problem 8.
A physicist makes many measurements of the frequency of light emitted when a electron transitions from a particular excited state of an ion. For the system she is studying, the only allowed transition from the excited state is to the ground state. Her measurements have an average value of favg=2.13×1015 Hz with a standard deviation of ?f=17.4×106 Hz.
What is the minimum lifetime Δtmin of the excited state in seconds?
An electron confined in a box of width 0.360nm makes a transition from the n = 1 to n = 4 level by absorbing a photon. Calculate the wavelength of this photon.
