What is the wavelength of the compression wave?
What is the magnitude of the maximum displacement of the compression wave?
What is the speed of the compression wave?
What is the period of the compression wave?
What is the maximum displacement of the sound wave?
What is the wavelength?
What is the frequency of the sound wave?
What is the speed of the sound wave?
A speaker is placed at the opening of a long horizontal tube. The speaker oscillates, creating a sound wave that moves through the tube at a speed of 340 m/s. The sound wave is modeled with the wave function , where is measured in meters and is measured in seconds. At time , an air molecule at the position is at the maximum displacement of 7.00 nm. At the same time, another molecule at the position has a displacement of 3.00 nm. What is the frequency at which the speaker is oscillating?
