How can the frequency of a wave be found?
multiply its speed by its wavelength
divide its speed by its wavelength
divide its wavelength by its speed
multiply its amplitude by its wavelength
The correct answer is: divide its speed by its wavelength.
The frequency of a wave can be found by dividing its speed by its wavelength. This can be represented by the formula:
frequency = speed / wavelength
where frequency is measured in hertz (Hz), speed is measured in meters per second (m/s), and wavelength is measured in meters (m).
