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 wavelength of the wave?

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

Answer 1

The correct option is D $0.02m$

Given : $f=4cycles/s,v=0.08m/s$

we have, $v=f\lambda$ (where $\lambda$ is the wavelength of wave)

or $\lambda =v/f=0.08/4=0.02m$
