Question

A sinusoidal traveling wave is generated on a string by an oscillating source that completes 116 cycles per minute. What is the wavelength of the wave if individual crests are observed to travel 11.0 m in 1.50 min?

Answer 1

`\lambda =6.32\ cm`

Step-by-step explanation:

given,

number of cycle complete (f) = 116 cycles per minute

wavelength observed at 11 m in 1.5 m.

`v = (distance)/(time)`

`v = (11)/(1.5)`

v = 7.33 m/s

`\lambda = (v)/(f)`

`\lambda = (7.33)/(116)`

`\lambda =0.0632\ m`

`\lambda =6.32\ cm`

The wavelength of the wave is equal to
`\lambda =6.32\ cm`
