Problem 2 Two speakers (emitting identical sound waves of wavelength 2.0 m in phase with each other) and an observer are located as shown in the figure below. Observer # T 8.0 m S " e v a) At the observer's location, what is the path-length difference for waves from the two speakers? e b) Will the sound waves interfere constructively or destructively at the observer's location - or something in between constructive and destructive? ) Suppose the observer now increases her distance from the closest speaker to 17.0 m, staying directly in front of the same speaker as initially. Answer the questions of parts a) and b) for the new situation. Problem 8 a) If the first-order maximum for pure-wavelength light falling on a double slit is at an angle of 10.0, at what angle is the second-order maximum? b) What is the angle of the first minimum? ) What is the highest-order maximum that is possible here
