Question

Q3. In an open organ pipe third harmonic is 450Hz. What is the frequency of fifth harmonic?​

Answer 1

Answer:

Freque n cy of the 5 th harmonic = 5 ν 1 3 ν 1 = 450 Hz ν 1 = 150 Hz 5 ν 1 = 150 × 5 = 750 Hz Therefore frequency of the fifth harmonic is 750 Hz .

Answer 2

Answer:

Frequency of the 3 rd harmonic = 3 ν 1 = 450 Hz where. Freque n cy of the 5 th harmonic = 5 ν 1 3 ν 1 = 450 Hz ν 1 = 150 Hz 5 ν 1 = 150 × 5 = 750 Hz Therefore frequency of the fifth harmonic is 750 Hz .
