Question

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

Answer 1

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).
