Two loudspeakers in a plane, 5.0 m apart, are playing the same frequency. if you stand 11.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. as you walk parallel to the plane of the speakers, staying 11.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. part a)what is the frequency of the sound? assume a sound speed of 340 m/s. i got 120.02 hz. this is right, i checked. part b)if you stay 12.0 m directly in front of one of the speakers, for what other frequencies between 100 hz and 700 hz is there a minimum sound intensity at this point?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
