Consider an electron in an infinite well of width 0.5 nm.
Given : h(bar) = 1.05457 x10^&#8722;34 J s ,
RH = 1.09735 x10^7 m&#8722;1 ,
a0H = 5.29177 x 10&#8722;11 m, and
E0H = 13.6057 eV .
What is the wavelength of a photon emitted when the electron in the infinite well makes transition from the first excited state to the ground state? Answer in units of nm.
