Question

A wave is travelling on a string with the frequency $4$ cycles per second, and its speed is 0.08 meters per second.
Calculate the time period of the wave?

• A. $0.25seconds$
• B. $0.55seconds$
• C. $3.125seconds$
• D. $0.02seconds$
• E. $12.55seconds$

Answer 1

The correct option is A $0.25seconds$

Given - $f=4cycles/s$

we have, time period

$T=1/f=1/4=0.25seconds$
