Question

The frequency of a sound wave is 25 Hz. What is the number of oscillations produced in 1 minute?

• A. $250$
• B. $50$
• C. $1500$
• D. $25$

Answer 1

The correct option is C $1500$

The number of oscillations per second is called the frequency of oscillation. A frequency of 25 Hz is 25 oscillations per second.

So, in 1 minute or 60 seconds the number of oscillations will be $25\times 60=1500.$
