Answer #1

SPEED OF SOUND
(Resonance Method)

1. PURPOSE:

To determine the speed of sound in air.

2. APPARATUS:

Resonance tube, assorted tuning forks, rubber bands, striking block, water.

3. THEORY:

(1) The frequency of sound in a medium is related to the wavelength by the formula v = f? where v is the speed of sound in the medium, f is the frequency of the sound, and ? (Greek letter "lambda") represents the wavelength of the sound in the medium. This formula is used to calculate the speed of sound in air from measurements of wavelength and frequency.

(2) The sound speed varies with temperature. At 0

A two-meter long pipe filled with water is open at one end and closed at the other. You have at your disposal a tuning fork with a frequency of 250 Hz and a noise meter (a device to measure the intensity of a sound in decibel). Using the tuning fork, you lower the water level until you hear the first three resonances. The first, second, and third resonances are at 0.35m, 1.05m and 1.75m respectively. At the same time, your...

For each of the following situations during the density of water experiment, determine if the mistake would give a falsely high or falsely low density for water. For each situation, assume everything else in the experiment is done correctly. Note: It may be helpful to try some hypothetical calculations. a. When weighing a volumetric flask full of water, a student does not notice that the outside of the flask is wet. ( Choose HIGH,LOW,or Unchanged). Explain Why? b. When weighing...
