Question

If a wave completes $24$ cycles in $0.8s$, the time period of the above wave would be (in seconds)

• A. 0.03
• B. 30
• C. 0.3
• D. none of these

Answer 1

The correct option is A 0.03

The time period is simply the time taken to complete one cycle.

Time $t$ for $24$ cycles $=0.8s$

Time $T$ for $1$ cycle $=\frac{totaltimetaken}{numberofcycles}=\frac{0.8}{24}$

$\therefore$ Time period $T=\frac{8}{240}=\frac{1}{30}=0.0333s\approx 0.03s$

Option A is the answer.
