Planck Time

Explanation

Another fundamental physical constant named after Max Planck, Planck time is the time that it takes for light to travel the distance of one Planck length.

Derivation – Planck Time

The equations in both the classical format and wave equation format of Planck time comes from the derivation of Planck length.  They are similar with the exception of the constant for the speed of light (c).  This is because Planck time is defined as the time that it takes for a wave traveling at the speed of light to travel the Planck length.
