Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 14.0 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 54.0 cm. What is the wavelength of the sound?
The wavelength of sound is 80 cm. (54-14=40 cm from crest to trough) So crest to crest is 80 cm.
