An aircraft maintenance technician walks past a tall hanger door that acts like a single slit for sound entering the hangar. Outside the door, on a line perpendicular to the opening in the door, a jet engine makes a 600 Hz sound. At what minimum angle with the door will the technician not be able to hear the roar of the engine? The vertical opening in the door is 0.800 m wide and the speed of sound is 340 m/s.

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
