Question

What is the wavelength of a wave if it has a speed of 10 meters/second and a frequency of 2 hertz

Answer 1

Important Formulas:

`v=\lambda f`

velocity(measured in m/s) = wavelength(measured in meters) * frequency(measured in hertz)

__________________________________________________________

Given:

`v=10m/s`

`f=2Hz`

`\lambda=?`

__________________________________________________________

Rearranging formula for velocity to make wavelength the subject:

`v=\lambda f`

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

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

__________________________________________________________

Finding wavelength:

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

`\lambda=(10)/(2)`

__________________________________________________________

Answer:

`\boxed{\lambda=5 \texttt{ meters}}`
