In an open organ pipe, third harmonic is 450 Hz . What is the frequency of fifth harmonic ?

Text Solution

Verified by Experts

For third harmonic frequency in an open organ pipe,
`n_(3) = 3n_(0)`
Here, ` n_(3) =m 450 Hz `
` :. 450 = 3n_(0) or, n(0) = 150 Hz `
for fifth harmonic , `n_(5) = 5 n_(0) `
Now, `n_(0) = 150 Hz `
`:. N_(5) = 5 xx 150 Hz or, n_(5) = 750 ` Hz
