The emitted quantum of energy is released in the form of a photon of light of characteristic frequency. This is seen as a colored line in the visible spectrum when the photon’s wavelength is between 400-750nm. For example, in high-voltage discharge tubes, various gases (e.g. neon) or vapours (e.g. sodium) are observed to emit light. The greater the intensity of the line, the more electrons falling and emitting radiation.[/cs_text][/cs_column][/cs_row][/cs_section][/cs_content]
