derivation for dispersion in gases (Lorentz theory )?
Answers
Answer:
The Lorentz classical theory (1878) is based on the classical theory of interaction between light and matter and is used to describe frequency dependent polariza- tion due to bound charge. ... At low frequencies ω<<ωt, the amplitude r has a me- dium finite value and is in phase with E.
Plugging either (1) or (2) into the equation yields an algebraic relationship of the form ω = ω(k) or σ = σ(k), called the dispersion relation. It characterizes the dynamics of spatially oscillating modes of the form exp(ikx). Here are a couple standard examples.
Dispersion is defined as the breaking up or scattering of something. An example of a dispersion is throwing little pieces of paper all over a floor. An example of a dispersion is the colored rays of light coming from a prism which has been hung in a sunny window.
Answer:
Conclusion. Electromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E = h ν E=h\nu E=hν , we have seen how the frequency of a light wave is proportional to its energy.
