Question

A sound wave completes $24$ cycles in $0.8s$. The time period of the wave would be:

• A. $1/30s$
• B. $30s$
• C. $1/24s$
• D. $24s$

Answer 1

The correct option is A $1/30s$

A time period is the time taken to complete one cycle.

Given that, the sound wave completes $24$ cycles in $0.8s$

So, the time taken to complete one cycle $=\frac{0.8}{24}=\frac{1}{30}s$

Hence the time period is $\frac{1}{30}s$
