Physics 2: Waves and Sound
If you are standing 100 m away from the starter at a track meet, how long will it take you to hear the sound from the gun after it is shot?
A concert A has a frequency of 440 hertz. What is its wavelength, and what is the frequency and wavelength of an A one octave higher?
The soda bottle in the above question is 1/3 full. What is the resonant frequency of sound produced when you blow across it?
An organ pipe is 78 cm long. What is the resonance frequency of sound it produced if it is: A. Open? B. Closed?
A wave travelling on a slinky has a period, T = 0.25 s, and a wavelength, = 0.3 m. Find the frequency and speed of the wave.
A 2 m long string is tied down at one end and held by a person at the other end. The mass of the string is 4 kg. The person pulls the string taut with a tension of 72 N and shakes the string with a frequency of 2 Hz to produce a standing wave. Find the wavelength.
A tube is open on one end and closed on the other. Find the largest and second largest wavelengths.
