The frequency of a source of sound is
$100Hz$. The number of sound wave produced in one minute is

• A. $6000$
• B. $600$
• C. $1000$
• D. $100$

Answer 1

The correct option is A $6000$

Given,
Frequency$=100Hz$

Therefore, number of waves produced 1 minute, i.e. in 60 seconds
$=100\times 60=6000$ times.
