One hertz is defined as how many oscillations per second?

ANine oscillations
BSixty oscillations
COne oscillation
DTen oscillations
Answer & Solution
Correct answer: C. One oscillation
1. The unit of frequency counts cycles against time. 2. Its definition is fixed at the simplest possible rate. 3. One hertz equals one oscillation per second. 4. So the answer is one oscillation. _Source: syllabus Physics Part II, Ch 13 'Oscillations'_
