alright so i am stuck on two questions and i have no idea how to solve them. so if people have a knowledge of this, help would be greatly appreciated
A complex waveform repeats itself every 1×101 ms (ms = millisecond). What is the fundamental frequency? Just enter the number without any units. (For you to think about: What are the first 4 harmonic frequencies including the fundamental?)
A saxophone is playing a steady note of freqency 825 Hz. The temperature in the room is 32 oC. At a given moment in time, the pressure at your eardrum is at a maximum. How far away from your ear is the next high pressure region in the air? (Find the answer in meters, but do not enter units.)

do 1/.101 and that gets you tha frequency in the first harmonic aka the fundamental frequency
then just double and triple and quad that bitch to get the next harmonics
if i emember correctly

1/.101 isnt right.
im out of tries on that problem now so it doesnt matter

If its .101 seconds per cycle then 1/.101 cycles per second which is frequency in hs. Chronic explained correctly what the harmonics are
For 2. The speed of sound equals the wavelength times the frequency. S=wf. So w=s/f
The speed of sound is v = 331m/s + 0.6m/s/C * T
So your speed of sound at 32 degrees is 350.2 m/s
So since w=s/f , W= 825hz/350.2 mps
W=2,36 meters
Don't expect any of the inferior toolbags on ns to explain that for you. Fucking tools on ns these days

I had the frequency and speed backwards the answer to 2 is 350.2mps/825hz=0.42 meters
