wo speakers, speakers 1 and 2, located 0.750 m apart from each other, are creating sound waves with an identical frequency of 686 Hz and are in phase. Assume the speed of sound in the room is 343 m/s. Your ear is directly in line with the speakers. a) Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location? b) You now go and stand directly in between the two speakers (0.375 m to the right of speaker 1 and 0.375 m to the left of speaker 2). Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location?

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.
