Compton scattering
... • It seems that high energy radiation can suffer less scattering and therefore can propagate more freely through the universe. Is that true? Can you think to other processes that can kill high energy photons in space? • Suppose to have an astrophysical source of radiation very powerful above say – 1 ...

Bohr`s atomic model
... relation together with Eq. 11 allows calculating the frequencies at which the hydrogen atom can absorb and emit light. Since the frequency ν is related to the wavelength λ by the relation c = λν (where c is the speed of light), we can also calculate the wavelengths at which hydrogen absorbs and emit ...
