Answer on Mechanics | Relativity Question for Becca
a) What is the fundamental frequency of this pipe.
b) Show why this is an open (at both ends) or closed ( one end open, one end closed) pipe.
If pipe can resonate at 264 Hz, 440 Hz and 616 Hz, then
440 Hz - 264 Hz = 176 Hz
616 Hz - 449 Hz = 176 Hz
This isn't an open pipe because the frequences are not multiples of 176 Hz . Therefore, it is a closed pipe with fundamental frequency f = 176 Hz /2 = 88 Hz.
The frequecies of organ pipe are:
88 Hz, 3×88 Hz, 5×88 Hz, 7×88 Hz
a) 88 Hz
b) it is a closed pipe
