100

Sound is an example of this wave 

What is longitudinal. 

200

An ear canal is an example of this tube. 

What is an open closed tube? 

300

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

2

100

Sound waves compared to light waves. 

What is slower?

200

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. 

300

2 notes are played on a piano with frequencies 468 Hz and 472 Hz. This is the beat frequency that will be heard. 

What is 4 Hz.

3

100

The medium sound travels fastest in 

What is solids?

200

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

300

The bandwidth is 50 and the fPeak is 545, this is the Q factor

10.9

100

Occurs when one object vibrates at the same rate as another item. 

What is Resonance

200

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

300

If the length of an open-closed tube is 0.25 m, then this is the wavelength of the 1st harmonic. 

1 m 

5

100

The range of frequencies that a resonator will respond to 

What is Bandwidth 

200

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

300

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
