How do you find photons

WebOne way of measuring single photons is to use a photomultiplier tube. Photons incident on the tube create an avalanche of electrons in each stage that can be detected as a current pulse. Photomultiplier tubes have sufficiently high gain to detect a single incident photon. WebTo obtain the photon energy, you need to multiply the velocity of the light ‘ c ’ in the vacuum by the Planck constant ‘ h ’ and divide this by the wavelength of the photon ‘ λ ’. The formula to obtain the photon energy is: Energy = c ⋅ h λ.

According to the Maxwell equations, all charges and currents are a source of the electromagnetic field, so to get photons from the Sun you must remove/supress the other possible sources. In other words, remove the "noise". A lot of work to do. phoneclaim number

WebEven though photons have no mass, they still interact with gravity because they have energy, and energy is affected by gravity. When light passes near a massive object like a star or black hole, the gravity bends space-time, causing the light to change its path. This is called gravitational lensing. how do you spell sherbert ice creamPhotons obey the laws of quantum mechanics, and so their behavior has both wave-like and particle-like aspects. When a photon is detected by a measuring instrument, it is registered as a single, particulate unit. However, the probability of detecting a photon is calculated by equations that describe waves. This combination of aspects is known as wave–particle duality.
