(Redirected from Planck's Constant)

**Planck's constant** "*h*" is a constant in physics that relates the energy of a photon to the frequency of that photon:

*E*=*h*ν

Where *E* is the energy of the photon and ν is its frequency.

The value of **Planck's constant** is approximately joule-seconds.
