Problem 21.19 Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 23cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 58cm.
Part A What is the wavelength of the sound? Express your answer to two significant figures and include the appropriate units.
Part B If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum? Express your answer with the appropriate units.
