Two identical loudspeakers that are 5.00 m apart and face toward each other are driven in phase by the same oscillator at a frequency of 875 hz. the speed of sound in the room is 344 m/s. if you start out standing midway between the speakers, find the shortest distance you can walk toward either speaker in order to hear a minimum of sound.

0.0982 m

Explanation:

Given

distance between two loudspeaker is 5 m

frequency (f )=875 Hz

speed of sound (v)=344 m/s

Let be the smallest distance moved by observer then

Position of observer w.r.t to first speaker is

Position of observer w.r.t to second speaker is

For Destructive interference

For minimum m=0

and

close lines strong magnet less close weaker
