Answer:
Frequency.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.
Mathematically, the speed of a sound is given by the formula:
Speed = wavelength * frequency
The pitch of a sound you hear depends on the frequency of the sound wave.
They get it from the experiment.
