Answer #1

The four important properties of a sound wave are listed below:

1) They are longitudinal in nature. This means the vibrations are parallel to the direction of motion of the wave.

2) They obey the wave equation , where i sthe velocity, f is the frequency and is the wavelength.

3) The frequency of the sound may appear different to observers in relative motion due to Doppler effect

4) They obey law of reflection, refraction, superposition.

5) They can not travel without a medium.

1. So far you have been using strings as the medium of wave oscillation. Now we will use air, which carries sound waves. You are given a plastic tube open at both ends. If your tube is less than 0.6m in length, look for an unused tube in another lab table and use that instead. You also have a speaker from which you can hear sound waves at different frequencies. Keep one end of the tube near the speaker. The...
