The length of an organ pipe closed at on...

The length of an organ pipe closed at one end is 90 cm . Find out the frequency of the harmonic next to the fundamental . Velocity of sound in air ` = 300 m* s^(-1)` .

Text Solution

Verified by Experts

A closed pipe emits the odd harmonics only . So the frequency of the harmonic next to the fundamental is
`n_(1) = 3 xx ` fundamental frequency
` 3 * (V)/(4l) = 3 xx ((300 xx 100))/(4 xx 90) = 250` Hz .
