You are inside a room, 15 m from the west wall, and centered between two open doors (like slits) that are 3 m apart on the west wall. Someone is blaring a 200 Hz tone outside the room so that it enters the doors as a plane wave. You hear a maximum intensity in your current position. As you walk (north) along the direction of the west wall with the doors (but maintain a distance 15 m from the wall), how far will you walk (in m) to hear a minimum in the sound intensity?
b. What is the spacing (in m) between maxima in sound intensity along that axis?
Please explain.

You are inside a room, 15 m from the west wall, which has two doors (similar to slits) and you are centered between the two open doors that are 3 m apart. Someone is blaring a 200 Hz tone outside the door so that it enters the doors as a plane wave. You hear a maximum intensity in your current position. a. As you walk (north) along the direction of the west wall with the doors (but maintain a distance...

You are standing 2.50 m directly in front of one of the two loudspeakers shown in the figure. They are 3.00 m apart and both are playing a 686 Hz tone in phase. (Figure 1) As you begin to walk directly away from the speaker, at what distances from the speaker do you hear a minimum sound intensity? The room temperature is 20 ∘C.

Two stereo speakers mounted 5.2 m apart on a wall emit identical in -phase sound waves. You are standing at the opposite wall of the room at a point directly between the two speakers. You walk 2.11 m parallel to the wall, to a location where you first notice that the sound intensity drops to zero. If the wall along which you are walking is 10.7 m from the wall with the speakers, what is the wavelength of the sound...

Interference waves of sound
1. Two loudspeakers 6.0 m apart are playing the same frequency. If you stand 10.0 m in front of the plane of the speakers, centered between them, you hear a sound ofmaximum intensity. As you walk parallel to the plane of the speakers, staying 10.0 in front of them, you first hear a minimum of sound intensity when you are directlyin front of one of the speakers. What is the frequency of the sound? Assume a sound speed of 340...

You are standing a distance d
(2m) directly in front of one of two identical speakers, being
driven by the same signal generator, that are a distance h (5m)
apart. You walk in the positive direction starting at y=0 m, along
a line parallel to the line joining the two speakers. The speed of
sound is 340 m/s and the frequency is 170 HZ. As you walk, how many
times and where will you hear a maximum sound?

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
