Question

Calculate the frequency of oscillation with the help of a given velocity-time diagram of a harmonic oscillator.

• A. $\text{25 Hz}$
• B. $\text{50 Hz}$
• C. $\text{12.25 Hz}$
• D. $\text{33.3 Hz}$

Answer 1

Answer: (A)

From the diagram, the time period of the wave is equal to $T=0.04s$ , The frequency of a wave is number of oscillation per unit time, so it is given by inverse of the time period, hence,
$f=\frac{1}{T}=\frac{1}{0 .04}=25Hz$ .
