Sounds waves are disturbances in air molecules that move at 343 m/s. Pitch is a measure of a sounds frequency. A middle C note in music has a frequency (pitch) of 261.6 Hz. a. If you are listening to a middle C, how many pulses (wave crests) of sound hit you in one minute (1 minute is exactly 60 seconds)? b. How far apart is each wave crest (wavelength) in a middle C note? c. If that note was sung...

1. The overall length of a piccolo is 32.0 cm. The resonating air column vibrates as in a pipe that is open at both ends. Assume the speed of sound is 343 m/s.

1. The overall length of a piccolo is 32.0 cm. The resonating air column vibrates as in a pipe that is open at both ends. Assume the speed of sound is 343 m/s. a. Find the frequency of the lowest note a piccolo can play (all holes are blocked) b. Find next three resonant modes of the piccolo when all the holes are blocked c. Draw diagrams of lowest 4 resonant modes, labeling all nodes and antinodes. d. Opening...

a) Kinetic theory. The speed of sound in the air is 330 m/s under standard conditions of temperature and pressure (273 K and 1 atm). Since the size of a molecule is much smaller than the average distance between the molecules, this number provides an estimate of the order of magnitude of the molecular media velocity. Consider a cubic meter of air and concentrate it on a N2 molecule that travels in the x direction at 330 m / s....

In a region where the speed of sound is 330 m/s, a source of sound emits a frequency of 440Hz. Assuming the observer is not moving, at what speed would the source have to move for the observed frequency to be 330Hz? Are they moving towards or away? A. Torwards B. Away C. This situation is not possible D. The Observer is at rest Part 2: Use the setup above. Enter the speed of the source with the units of...

In a location where the speed of sound is 332 m/s, a 2,000 Hz sound wave impinges on two slits 30 cm apart. (a) At what angle is the first-order maximum located? ° (b) If the sound wave is replaced by 4.60 cm microwaves, what slit separation gives the same angle for the first-order maximum? cm (c) If the slit separation is 1.00 μm, what frequency of light gives the same first-order maximum angle? Hz
