A.) I start with a bar 1.82 meters long. How long must I make a second bar to be a perfect fifth above the first? B.) A vibrating bar has a fundamental frequency of 423 Hz. Find the frequency of the 3rd overtone and bring it down by

The C major musical scale has notes C D E F G A B C in order.  Select the answers that apply.     There are half steps between E and F and between B and C.     There are no half steps. The frequencies are uniformly spaced.     The scale spans a factor of 2 in frequency.     Every note is  separated  from the one before it by a half step.

The Wanamaker Pipe Organ in Macy's Center City department store in Philadelphia is the largest working pipe organ in the world. The organ occupies a seven- story hall, and has the longest pipe length of 9.75 m that occupies four floors and can be used as either an open or a closed pipe. Assume that the speed of sound is 345 m/s. a. Calculate the lowest fundamental frequency for the Wanamaker Pipe Organ. b. The highest note on an 88-key piano is 4186 Hz. What would be the length of a pipe open on one end that produced this as a fundamental frequency?

One end of a wire is vibrated by a vibrating rod with a frequency of 5Hz and an amplitude of 16cm, so that the vibration propagates to the right along a wire with a speed of 20 m/s. Define: a. The general equation for the displacement of a traveling wave is, b. the velocity and acceleration of the particle at point x = 38.5 m when the end of the wire is vibrating 1,5 s c. the maximum speed and acceleration of any particle along the wire d. the phase angle and phase of the wave at point x = 38.5 m when the end of the wire has vibrated 1.5 second e. phase difference distance between two particle which separated on of 1.5 m.
