What is longitudinal.
Sound waves compared to light waves.
What is slower?
The medium sound travels fastest in
Occurs when one object vibrates at the same rate as another item.
What is Resonance
The range of frequencies that a resonator will respond to
An ear canal is an example of this tube.
A complex wave is formed by 2 waves. It has a repeat frequency of 300 Hz. If one of its waves has a frequency of 400 Hz this is the frequency of the other wave.
300 Hz.
Your vocal tract is 0.15 m long and you shout a note towards a mountain producing a standing wave in the 5th harmonic. The speed of air is 340m/s. The frequency of the note was 430 Hz, this is the wavelength.
0.12 m
If the fpeak is 624 Hz and the bandwidth is 72 Hz, this is the upper and lower cutoff.
Lower cutoff=588 Hz
Upper Cutoff=660 Hz
You shout, "Complex Waves are sooo cool!" towards a far mountain. If the speed of sound is 340 m/s and you hear an echo 3.2 seconds later. This is how far the mountain is.
What is 544 m
The bandwidth of a band pass filter is 200 Hz and the upper cutoff frequency is 920 Hz. Will a 830 Hz signal travel through?
Yes
What is 4 Hz.
The bandwidth is 50 and the fPeak is 545, this is the Q factor
10.9
If the length of an open-closed tube is 0.25 m, then this is the wavelength of the 1st harmonic.
1 m
Four waves with frequencies of 150 Hz, 170 Hz, 230 Hz, and 260 Hz make upa complex wave. This is the repeat frequency
150 Hz
