WebFeb 18, 2024 · When talking about photons, the velocity is c c, a fundamental constant in physics. Knowing that \nu = \tfrac {c} {\lambda} ν = λc, where \lambda λ is the wavelength, we can derive the equation of the energy of a photon from the wavelength: E = \frac {h\cdot c} {\lambda} E = λh ⋅ c WebEach particle of electromagnetic radiation, called a photon, has certain amount of energy. Types of radiation with short wavelengths have high-energy photons, whereas types of radiation with long wavelengths have …
WebApr 9, 2024 · Kmax = hv - W. Here W is the work function of the metal. It is the minimum energy that needs to be supplied to the metal body for the emission of photoelectrons. Now W can be written as: W= hvo. Here vo is the photoelectric threshold frequency of the electromagnetic rays. WebHowever, because short-wavelength photons carry more energy per photon, the maximum amount of photosynthesis per incident unit of energy is at a longer wavelength, around …
