Two sound sources driven in phase by the same amplifier are 2 m apart on the y?axis. At a point a very large distance from the y?axis, constructive interference is first heard at an angle ?₁ = 0.140 rad with the x?axis and is next heard at ?₂= 0.283 rad (see Figure).

(a) What is the wavelength of the sound waves from the sources?

(b) What is the frequency of the sources?

(c) At what other angles is constructive interference heard?

(d) What is the smallest angle for which the sound wavescancel?
