Photon wavelength spectrum
WebThe dark lines in the emission spectrum of the sun, which are also called Fraunhofer lines, are from absorption of specific wavelengths of light by elements in the sun's atmosphere. The side-by-side comparison shows … WebOnly occasionally will the light be emitted in the direction of the original photon. As a result, you will see a dimmer area in the narrow wavelength region where the photon energy corresponds to the atomic energy transition. On either side of that dark line, the spectrum will be unaffected, showing its normal brightness.
