How can you find the wavelength of a longitudinal wave?

Answer 1

Use the formula

f = v λ

Where f is frequency, v is the speed of the wave, and λ is the wavelength.

Dividing both sides by v gives

λ = f / v

Answer 2

To find the wavelength of a longitudinal wave, you can measure the distance between two consecutive compressions or rarefactions. This distance represents one complete cycle of the wave and corresponds to the wavelength. Alternatively, you can use the wave speed formula (speed = frequency x wavelength) to find the wavelength if you know the speed and frequency of the wave.
