Question

Ms. Lawson is making a video about waves. In the video she wiggled a string to create a transverse wave. The wave had a wavelength of 2.0 m and speed of 1.5 m/s. What was the frequency of the wave?

Answer 1

Answer: The frequency of the wave is
`0.75s^(-1)`

Step-by-step explanation:

The relationship between wavelength and frequency of the wave follows the equation:

`\\u=(c)/(\lambda)`

where,

`\\u` = frequency of the wave = ?

c = speed of the wave =
`1.5m/s`

`\lambda` = wavelength of the wave =
`2.0m`

Putting in the values we get:

`\\u=(1.5m/s)/(2.0m)=0.75s^(-1)`

Thus the frequency of the wave is
`0.75s^(-1)`
