Question

Quizplus · Accepted Answer

The Planck constant has units of angular momentum, specifically joule-seconds (J·s) in SI units. This is because it relates the energy and frequency of a photon or other quantum particle to its angular momentum through the formula E = hf, where E is energy, f is frequency, and h is Planck's constant.
