To calculate the wavelength of a wave from its frequency and velocity, you can use the formula:
Wavelength (λ) = Velocity (v) / Frequency (f)
In this formula, the wavelength (λ) is measured in meters, the velocity (v) is measured in meters per second, and the frequency (f) is measured in hertz (Hz).
To use the formula, simply divide the velocity of the wave by its frequency, and you will obtain the wavelength. For example, if you have a wave with a frequency of 100 Hz and a velocity of 300 meters per second, the calculation would be:
Wavelength (λ) = 300 m/s / 100 Hz = 3 meters
Therefore, the wavelength of the wave in this example would be 3 meters.
