Two loudspeakers 42.0 m apart and facing each other emit identical 115 Hz sinusoidal sound waves in a room where the sound speed is 345 m/s. Susan is walking along a line between the speakers. As she walks, she finds herself moving through loud and quiet spots. If Susan stands 19.5 m from one speaker, is she standing at a quiet spot or a loud spot?
Speakers A and B are vibrating in phase. They are directly facing each other, are 8.80m apart, and are each playing a 100 Hz tone. The speed of sound is 340m/s. On the line between the speakers there are points where maximum sound intensity occurs. What is the distance of the nearest point from speaker A?
Two audio speakers have been arranged in a large room so as to produce a sound interference pattern. Miguel starts at a position on the central antinodal line and begins to slowly walk parallel to the imaginary line connecting the speakers. Miguel stops at the first position of minimum loudness. At this position, he is a distance of 17.9 m from the nearest speaker. Sound waves travel through the room at 345 m/s and the speakers are sounding out a frequency of 244 Hz.a. Determine the wavelength of the sound waves.b. Determine the distance from Miguel to the furthest speaker.
