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.
