WebLine spectra were first observed and studied in the latter half of the 19th century, but it was only in the 1920s that a full explanation was finally developed. To explain the energy emitted by atoms, a new branch of … WebThese emitted photons have energies equal to the differences in the atomic energy levels. In this experiment, an electrical current provides the energy to excite the atoms. Some of the emitted photons have energies in the visiblo region of the spectrum, so we can obsorve thom directly and make measuroments by which wavelengths, frequencies, and ...
WebLine Spectra Electromagnetic radiation emitted from heating some substance, like a volatile salt, can be incident on a substance to give an electromagnetic spectrum. Coloured lines are obtained, separated by dark gaps. The coloured lines occur at the same places where dark lines were obtained in absorption spectra. Such spectra are known as ...

WebShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency.
