Which equations could be used as is, or rearranged to calculate for frequency of a wave? Check all that apply.

1. wavelength = frequency / speed

2. speed = frequency x wavelength

3. wavelength = speed / frequency

4. frequency = speed / wavelength

5. frequency = wavelength over speed

6. speed = wavelength x frequency

- - Equations #2 and #6 are both the same equation,

and are both correct.

- - If you divide each side by 'wavelength', you get Equation #4,

which is also correct.

- - If you divide each side by 'frequency', you get Equation #3,

which is also correct.

With some work, you can rearrange this one and use it to calculate

frequency.

Summary:

- - Equations #2, #3, #4, and #6 are all correct statements,

and can be used to find frequency.

- - Equations #1 and #5 are incorrect statements.
