Question

Loudspeakers A and B are vibrating in phase and are playing the
same tone, which has a frequency of 400 Hz. They are set up as in
the figure, and point C is located as shown there. However, the
distance between the speakers and the distance between speaker B
and point C have the same value d. The speed of sound is 343 m/s.
What is the smallest value of d, such that constructive interference
occurs at point C?
90
