alleryStart learning →A wave has a frequency of 10 Hz. What is its period?
A10.0 s
B1.0 s
C0.1 s
D100.0 s
Answer & Solution
Correct answer: C. 0.1 s
1. Period is the reciprocal of frequency: T = 1/f.
2. Substituting: T = 1 / 10 Hz = 0.1 s.
3. 100 s would come from multiplying by 10 instead of dividing.
