In her physics lab Maria finds that she can take a long glass tube and fill it with water using the air space at the top to simulate a pipe closed at one end. Maria holds a tuning fork which vibrates with a fundamental frequency of 440 Hz over the mouth of the pipe how long is the air column if it vibrates with the same frequency?

The denizens of a distant planet live under an atmosphere made predominately of CO2, which is a dispersive medium. While attending a concert, which of the following would be true for a spectator seated in the back of a large amphitheatre? I. They would hear the low notes and high notes at the same time. II. They would hear the low notes and high notes at different times. III. They would hear nothing because sound can't propagate in CO2.

4. You are riding your bike down a hill at a speed of 7 m/s (~15 mph) and a stationary bell is ringing at the bottom of the hill with a pitch that has a frequency of 320 Hz. What wavelength would you measure for sound and what frequency would you hear? Use v = 340 m/s for the speed of sound. - wave

6. Oscillations and sounds:a.A wave with wavelength 27 m and time between crests of 0.5 s is traveling in water. What is wavelength, frequency,period, and the wave speed? b. You blow into one end close pipe and produce a tone. Explain what happens to the frequency of the tone if you open both ends of the pipe and blow into it again? c. A car moving away from you at the speed of 50.0 m/s while you are standing on the sidewalk. The engine produces sound at 27 Hz and the speed of sound is 340 m/s. What is the frequency you hear?
