WebCompton Shift. The quantity h/mc in is a constant called the Compton wavelength.Its value depends on the rest mass m of the particle from which the x rays scatter. Figure below shows his results. Although there is only a single wavelength (λ = 71.1 pm) in the incident x-ray beam, we see that the scattered x rays contain a range of wavelengths with two … WebPhotoelectric Effect First observed in 1839, by Alexandre Edmond Becquerel.
