WebOct 21, 2024 · The spectral irradiance is given as a function of wavelength λ, and gives the power (energy per unit time) received by the surface for a particular wavelength of light. It is given by the equation: where F (λ) is the spectral irradiance in terms of photon flux Φ, energy of a given photon E, and the wavelength of the given photon λ. WebShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency.
