Planck's quantum hypothesis is an ad hoc assumption that radiant energy could exist only in discrete quanta, proportional to the frequency.
This assumption is used to explain the frequency distribution of radiation from a hot cavity.
The energy of oscillation of atoms is expressed as E = nhf
Which of the following statements are true concerning Planck's quantum hypothesis?
Check all that apply.
A. An upper limit is set on the amount of energy that can be absorbed or emitted in oscillations.
B. A lower limit is set on the amount of energy that can be absorbed or emitted in oscillations.
C. The energy of the oscillations of atoms within molecules can have any value.
D. The energy of the oscillations of atoms within molecules must be quantized.
