उत्तर
Two sounds A and B are of same amplitude, same wave forms but of frequencies f and 2f respectively. Then B is shrill, A is grave.
Explanation:
The shrillness or pitch of a sound is directly proportional to the frequency of the sound wave. The greater the frequency, the shriller will be the note.
