“Light is the purest form of kinetic energy”.If you are wondering about the relevance of this statement, it has been made because light has no mass and as such, it cannot exert a force upon a particle of matter.

If you are referring to the exchange of kinetic energy, then this article has absolutely no quarrel with that definition.If, however, you are defending the concept of the ‘absorption and emission’ of photons by an electron, then all I need is a clear explanation of how photons are physically absorbed into an electron and then re-emitted again and I will happily stand down.
“Light is the purest form of kinetic energy”.To develop an alternative explanation to the concept of ‘electron jumping’, we can progress by taking a different interpretation of Plank’s formula of E=hf, where E is the kinetic energy generated by light photons of a specific frequency passing through a unit area per second, f is the photon frequency in cycles per second and h is Plank’s constant.The formula as above, is correctly applied in its role of measuring the flow of kinetic energy through a unit area, but it is a mistake to make the assumption that the photon frequency, f and the kinetic energy, E are linearly correlated. By interpreting the formula without its ‘time dimension’ and setting the frequency of a photon at ‘one quantum cycle’, then E becomes the kinetic energy carried by one ‘wave cycle’ of a photon and h is the measurement of the photon’s energy content.The conclusion of this adaption of the formula is that every photon of light, whatever its frequency, carries exactly the same amount of kinetic energy and its magnitude is Plank’s constant.
