How can an energy, equivalent to a kinetic energy during its instantaneous encounter with an electron, be proportional to a frequency measured over one second?

How can we explain the coincidence that the value of “h,” if we take it as energy in joules, whatever the frequency, corresponds to the energy of a cycle?

How can we not see that in both forms of Planck’s law, we have a remarkable element “λ^-2” in front of the system unit “m^-2”?
