Question

In the quantum theory of hydrogen, as an electron drops to lower EPE orbit, it emits a photon with missing energy equal to O (Am) c2 AQ, i.e., themal equilibrium O A(EPE)

Answer 1

$\Delta (EPE)$

****************

if the wavelength is a lot bigger than the gap, there will not be much diffraction

*****************

A countable set of colors, as opposed to a continuous ROY G BIV spectrum from a thermal source.

******************

constructive interference occurs for that wavelength $\lambda_1$ at that exact angle
