Doppler Effect is the increase or decrease in light, sound or other waves when the source and observer move towards or away from each other. This effect gives rise to not just a crucial theory of physics but also helps in mathematical calculation of waves and their frequencies. Before proceedi...

Now, let us derive the formula for Doppler frequency.Derivation of Doppler FrequencyThe distance between Radar and target is nothing but the Range of the target or simply range, R. Therefore, the total distance between the Radar and target in a two-way communication path will be 2R, since ...
The formula for the frequency shift of a plane-polarized light wave reflected from a uniformly moving mirror is derived directly from the constant light speed postulate and the basic principles of wave optics. Unlike the original derivation by Einstein, our derivation does not involve Lorentz transfo...
The Doppler Effect as It Is 来自 ResearchGate 喜欢 0 阅读量: 6 作者:B Rothenstein,W Stahli 摘要: We present a derivation of the formula that accounts for the Doppler shift in a monochromatic electromagnetic wave, free of the "plane wave" or "very high frequency assumption". For the limit...

Wien and Stefan–Boltzmann laws have showed that there is a relation between temperature and wavelengths, but Planck had got lost in his derivation. Einstein later suggested (postulated) that this mathematical artifact “must” be interpreted as quantum-unit. Planck’s measured value 6....
In addition to a derivation of exact formulae for the spectra, we give an explanation with the help of an appropriate set of dressed atomic states. We also get a deeper insight into the physical origin of gain in view of the existence of a population inversion between the levels of the ...
How is the Doppler effect in an accelerating frame mathematically calculated? The mathematical formula for calculating the Doppler effect in an accelerating frame takes into account the relative velocity between the source and observer, as well as the acceleration of the frame. This can be expressed...
A detailed account is presented of the Doppler effect as a photon phenomenon, complementing a recent paper by Giuliani (2013 Eur. J. Phys. 34 1035-47). The essence of Schrodinger's pioneering derivation (1922 Phys. Z. 23 301-3) of a Doppler formula in terms of the corpuscular theory ...
