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.

A) You attend an open-air concert with a friend on a hot day with an air temperature of 25.3°C, and the arena has two speakers, one on each side of the stage. Suppose you sit in a seat which is 7 meters from one speaker and 9.1 meters from the other, and your friend sits in a seat 7 meters from one speaker and 8.75 meters from the other. If a musician plays a single 494 Hz tone through the...

Two loudspeakers at an outdoor rock concert are located 3.9 meters apart. You are standing 15.1 meters from one of the speakers and 19.6 from the other. During a sound check, the technician sends the exact same frequency to both speakers while you listen. The technician starts at 20Hz and slowly increases it to 30,000Hz. 1) What is the lowest frequency where you will hear a minimum signal ? 2) What is the second lowest frequency where you will hear...

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?

Q3M.1 You are setting up a pair of PA speakers on a field in paration for an outdoor event. Each speaker is 0.65 m wide, and the speakers are separated by 8.2 m. To test the speakers, your coworker plays a single tone through the speakers whose frequency is 440 Hz. You are standing 52 rm directly in front of the speakers and facing them. Roughly how far would you have to walk to your left or right to hear...

You are listening to a speaker on a tripod in a room with a nice
smooth marble floor, as shown in the figure below. The speaker
emits sound of wavelength (lambda). The speaker s and your ear e
are the same distanceh above the floor. Your ear and the speaker
are a distance d = 4 h away from one another.
Not only does your ear sense the sound wave moving along path 1,
but your ear also senses the...

I know how to do the first 3 parts. Need last 3 parts of the question. Posted whole thing for reference. Thanks! a) A 1 meter long guitar string of linear mass density 2g/m3 is put under tension until it resonates with a fundamental frequency of 440 Hz. Determine the tension that produces this fundamental frequency. Also determine the other of the first four harmonic frequencies and draw diagrams illustrating what each of these oscillations looks like on the string....
