Two loudspeakers are placed side by side a distance d = 4.00 m apart. a listener observes maximum constructive interference while standing in front of the loudspeakers, equidistant from both of them. the distance from the listener to the point halfway between the speakers is l = 5.00 m . one of the loudspeakers is then moved directly away from the other. once the speaker is moved a distance r = 60.0 cm from its original position, the listener, who is not moving, observes destructive interference for the first time. find the speed of sound v in the air if both speakers emit a tone of frequency 700 hz .

What are the three ways that an object can accelerate

During which interval are the persons represented by the graph not moving? a) 0 to 0.5 hrs b) 1.5 to 2 hrs c) 2 to 2.5 hrs d) 4.5 to 5 hrs

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
