Question 132: Oscillations

Question

A closed organ pipe has a fundamental frequency of 1.5 kHz. The number of overtones that can be distinctly heard by a person with this organ pipe will be (Assume that the highest frequency a person can hear is 20,000 Hz)

Accepted Answer

For closed organ pipe, resonate frequency is odd multiple of fundamental frequency.
$$ 	herefore $$  (2n + 1) f
0
$$ \le $$ 20,000
(f
0
is fundamental frequency = 1.5 KHz)
$$ 	herefore $$  n = 6
$$ 	herefore $$  Total number of overtone that can be heared is 7. (0 to 6)
