WebSep 4, 2024 · This phenomenon also accounts for the emission spectrum termed as a hydrogen emission spectrum. The emission spectra of molecules are commonly used in the chemical analysis of elements. • The hydrogen spectrum is a significant piece of evidence that further shows that the electronic structure of the atom is quantized. WebSep 21, 2024 · The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm. With sodium, however, we observe a yellow color because the most intense lines in its spectrum are in the yellow portion of the spectrum, at about 589 nm.
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an electron making a transition from a high energy state to a lower energy state. The photon energy of the emitted photon is equal to the energy difference between the … See more In physics, emission is the process by which a higher energy quantum mechanical state of a particle becomes converted to a lower one through the emission of a photon, resulting in the production of See more Light consists of electromagnetic radiation of different wavelengths.
