Two loudspeakers X and Y emit sound waves that are in phase and of wavelength 0.75 m.
An observer O is able to stand anywhere on a straight line that passes through X and Y, as shown. The observer stands at a point where the sound waves from X and Y meet in phase.
What could be the distances OY and XY?
