1. One way to think of the units of h is that, because of the equation E = hf and the fact that f is in cycles/second, then the “explicit” units for h should be J · s / cycle. Then, since 2 π rad/cycle is a conversion factor for cycles radians, ¯ h = h/ 2 π can be thought of as the Planck constant expressed in
