Reduced Planck Constant
type: PhysicalConstant
description: The $\textit{Reduced Planck Constant}$, or $\textit{Dirac Constant}$, is used in applications where frequency is expressed in terms of radians per second ($\textit{angular frequency}$) instead of cycles per second. In such cases a factor of $\pi$ is absorbed into the constant.
