qn 2
speed of sound divide by 0.70
so 344/0.70 is freq 1
freq 2 answer in freq 1 times 2
freq 3 answer in freq 1 times 3
Please help I cant breath with this qn, due today exam pending, thanks for taking your time to help.
The human outer ear contains a more-or-less cylindrical cavity called the auditory canal that behaves like a resonant tube to aid in the hearing process. One end terminates at the eardrum (tympanic membrane), while the other opens to the outside. (See the figure (Figure 1) .) Typically, this canal is approximately 2.21cm long.
