WebOther than photon counts, you also need to know the following parameters: 1)wavelength of the photons; 2) photon counts per second; 3) S= area of illumination. The photon energy can use this ... WebTemperature is a measure of average kinetic energy or also related to the wavelength of the photon. If you have enormous quantity of microwave range of photons the temperature anywhere may not rise above 3K. Classically and close to reality it is Weins displacement law that determines temperature in a spectrum. Share.
WebEach photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector. The frequency of a … WebOrdinary particles have a wavelength so small that we can't see the oscillations (this is because ordinary particles have mass). Photons, on the other hand, do not have mass. Their nonexistent mass and high speed (speed of light, c) cancel out nicely to produce noticeable wave like behavior. Comment ( 7 votes) Upvote Downvote Flag more Alex …
