Photon wavelength spectrum
WebA photon is a measurement on a quantum field. It's a "one time deal", if you like. Each photon has an energy and a helicity (sometimes confused with "spin"), but that's not enough to produce a "wavelength", which is a property of a classical electromagnetic wave. WebWhy does the light emitted from an electrically excited gas have only certain colors, while light given off by hot objects has a continuous spectrum? For a long time, it was not well explained. Particularly simple was the spectrum of hydrogen gas, which could be described easily by an equation; no other element has a spectrum that is so predictable (Figure 8.4 …

Web(a) Calculate the wavelength of a photon with an energy equivalent to that of an O=O bond ( 120 kcal/mol) (b) In what region of the electromagnetic spectrum does this wavelength fall? (c) If you wanted photons with energy greater than the O=O bond, would you want longer or shorter wavelengths than that which you just calculated? WebJul 24, 2024 · Visible red light with a wavelength of 700 nm, for example, has a frequency of 4.29 x 10 14 Hz, and an energy of 2.84 x 10-19 J per photon or 171 kJ per mole of photons (remember Avogadro’s number = 6.02 × 10 23 mol −1). The full range of electromagnetic radiation wavelengths is referred to as the electromagnetic spectrum.
