alleryIs the frequency of an oscillation necessarily a whole number?
AYes, it always is
BYes, if it is fast
CNo, unless it is slow
DNo, it need not be
Answer & Solution
Correct answer: D. No, it need not be
1. Frequency is defined as a reciprocal of a time interval.
2. Nothing in that definition forces a whole number.
3. The frequency is not necessarily an integer.
4. So it need not be a whole number.
