Question

A: Imagine you are a flagger between 2 jets. You are facing forward and so are the jets. Both of these jets create a sound wave in phase at 740 Hz. If you are 20 meters from the jet on your left, and 26 meters from the jet on your right, will the sound that you hear between the jets be an example of constructive or destructive interference? Sound=343 m/s

B: You are suddenly plagued with the loss of vision but you feel the need to jog forward at a steady pace of 2 m/s. The jets slowly roll in the same direction at 1 m/s just as you begin to walk forward. The forward direction that you are jogging in is perpendicular to the line joining the jets together. How far from your original stance must you jog until you cannot hear the jets anymore?
