Question
Two sounds A and B are of same amplitude, same wave forms but of frequencies f and 2f respectively. Then ______.
Options
B differs in quality from A
B is grave, A is shrill
B is shrill, A is grave
B is louder than A
Solution
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.
