The quantization of energy, E = nhf, is not important for an ordinary pendulum because:
A)the formula applies only to mass-spring oscillators
B)the allowed energy levels are too closely spaced
C)the allowed energy levels are too widely spaced
D)the formula applies only to atoms
E)the value of h for a pendulum is too large

Quizplus · Accepted Answer

The quantization of energy formula is not important for an ordinary pendulum because the allowed energy levels are too closely spaced. The quantization of energy formula applies to systems with discrete energy levels, such as atoms, where the allowed energy levels are widely spaced. In the case of a pendulum, the energy levels are continuous and closely spaced, so the quantization formula is not applicable.
