Frequency & wavelength practice
In the same medium, sound speed stays constant. What happens to wavelength when frequency increases?
Make your prediction
Now move the frequency
Watch the distance between the peaks. The arrow marks one wavelength.
Lower frequencyHigher frequency
Higher frequency means a shorter wavelength.
The relationship: sound speed = frequency × wavelength. This model changes frequency while keeping the medium and sound speed fixed. It illustrates spacing; it is not a real-time ultrasound waveform.
