The entrance to a large lecture room consists of two side-by-side doors, one hinged on the left and the other hinged on the right. Each door is 0.740 m wide. Sound of frequency 708 Hz is coming through the entrance from within the room. The speed of sound is 343 m/s. What is the diffraction angle of the sound under each of the following situations?
