Question:

A gas consists of atoms of mass m being in thermodynamic equilibrium at temperature T. Suppose wo is the natural frequency of light emitted by the atoms.
(a) Demonstrate that the spectral distribution of the emitted light is defined by the formula I∞ = I0e–a(1 - ∞/w0)2.
(Io is the spectral intensity corresponding to the frequency wo, a = mc2/2kT).
(b) Find the relative width ∆w/ wo of a given spectral line, i.e. the width of the line between the frequencies at which Io = Io/2.
Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
