1) Two speakers are emitting sound in phase. Michael is standing at a position where the difference in the path from the two speakers is 1.16 m. What is the maximum wavelength of the sound if Michael hears the minimum loudness?

2) Two speakers are in-phase and playing sound with frequency 242 Hz.Pam stands a distance of 5.86 m from one speaker. What is the minimum distance from the second speaker that she must stand in order to hear the minimum loudness?

You may assume the speed of sound in air is 343 m/s.

3)

Oscar begins to walk away from speaker 1 [along the path y as shown]. How far [in metres] is Dsear from speaker 1 when he hears laud spend fer the last time? Oscar and the speakers Two speakers are playing sound with frequency 610 Hz in phase. The speakers are separated by d = 2.25 m and Oscar initially stands very close to speaker 1 as shown. You may assume the speed of sound in air is 343 m/s. 1 d 2
