Explanation:

Justification: The frequency determines the shrillness or pitch of a sound. If the frequency of vibration is higher we say that the sound is shrill and has a higher pitch. If the frequency of vibration is lower, we say that the sound has a lower pitch. The vocal cords in men are about 20mm long. In women these are about 5mm shorter. Children have very short vocal cords. Just like a shorter elastic band produces a greater pitch when twanged, similarly women’s shorter vocal cords produce a higher pitch on vibration. This is the reason why the voices of men, women and children are different.
