Mass of a photon in kg
Webproton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10 −27 kg, which is 1,836 times the mass of an electron. Webphoton at the atomic clock frequency ν Cs has now a defined energy of h ν Cs . Using Einstein’s famous formula E=m c2, this gives the photon generated by the cesium clock transition a relativistic mass of h ν Cs /c2 = (1/1.4755214 1040) kg. Or in other words, one kilogram is now defined to be the mass of 1.4755214 1040

But I will provide you weight, rest mass, and total mass. Relativistic Mass: m = {E\over{c^2}} We can find the energy of a blue light an red light photons computed at: Photons So for blue light: m = 2.67\,{eV\over{c^2}} = {4.9...
WebViewed 3k times 3 The problem has a flame emitting a wavelength of 589 n m, and asks for the mass of one photon of that wavelength. It tells me that 1 J = 1 k g ⋅ m 2 s 2. I … Web$\begingroup$ Yes, to the extent that your unit system allows it (like $\frac{MeV}{c^2}$ for mass) I agree that the energy of the photons can be looked at as "just the energy". My question is sufficiently answered by nothing that this photon relativistic mass or energy (which one you use is semantics) exhibits all of the properties expected of that quantity …
WebThe new kilogram definition fixes the relativistic mass of a photon at the Cs hyperfine frequency as m ph = 6.777 265 × 10 −41 kg. Because total energy is conserved, if a Cs atom absorbs a photon of frequency ν Cs and transitions to its higher-energy hyperfine state, its mass must increase by m ph .
