This ratio is the Planck constant, denoted h, with a value of 6.626 ×10^{−34} Joule seconds.

Explanation:

The energy, E, of a photon is given by the equation:

E = h*f

where f is the frequency of the light (sometimes denoted as nu).

Thus:

E/f = h

and h is the Planck constant, which has a value of 6.626 ×10^{−34} Joule seconds.
