Todays class we read out of our yellow booklets, which consists of our Sound Unit... Starting from page 19 continuing until 22.. (I think). Following the reading, we were assigned questions 22, 23, 26 & 27, which are all on page 29 of the booklet.

Answers to the questions are:

22) (5/4) x 384 = 480 Hz -> B Note.

23) a. Fundamental Frequency = largest one, or line at the far left.
b. number of Harmonics would not be the same
c. White Noise would have all the same size bars


26) C4 = 256 Hz
C5 = 512 Hz (1 octave)
C6 = 1024 Hz (2 octave)

27) Both instruments produce harmonics for the fundamental frequencies. But the amplitude and harmonics are different.
Awot is to scribe for Friday.

Waves in 2D Test

Sorry I'm late, but had work.. anyways, today's class was our test which covered the Waves in Two Dimensions unit. The test wasn't THAT bad, it could of been worse. Most students took almost the entire class to complete the test, so that was basically all we had accomplished today.
