Two identical loudspeakers are driven in phase by a common oscillator at 790 Hz and face each other at a distance of 1.20 m. Locate the points along the line joining the two speakers where relative minima of sound pressure amplitude would be expected. (Take the speed of sound in air to be 343 m/s. Choose one speaker as the origin and give your answers in order of increasing distance from this speaker. Enter 'none' in all unused answer boxes.)
| Minima | Distance
from speaker (m) |
| 1st |
If the speakers are driven in phase, will an antinode or a node occur at the midpoint between the speakers? |
| 2nd | What is the relationship between the wavelength and the distance between nodes? |
| 3rd | |
| 4th | |
| 5th | |
| 6th | |
| 7th |
This is my third time posting this same question please solve correctly and show the value for the 7th minima thank you.

1. Two identical loudspeakers are driven by the same oscillator at frequency 480 Hz. They are located on the ground a distance of 4.0 m from each other. Starting far from the speakers, a man walks straight toward the right-hand speaker as shown. How many maxima does the man walk through and at what distances from the speaker are the maxima?

Two in-phase loudspeakers are 3.00 m apart. They emit sound with a frequency of 490 Hz. A microphone is placed half-way between the speakers and then moved along the line joining the two speakers until the first point of constructive interference is found. At what distance from that midpoint is that first point? The speed of sound in air is 343 m/s. Please work with this example.

Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 711 Hz to 1124 Hz. A point P is located 5.1 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which destructive interference occurs at point P, in SI units, is closest to: Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator,...

Loudspeakers A and B are vibrating in phase and are playing the
same tone, which has a frequency of 420 Hz. They are set up as in
the figure, and point C is located as shown there. However, the
distance between the speakers and the distance between speaker B
and point C have the same value d. The speed of sound is
343 m/s. What is the smallest value of d, such that
constructive interference occurs at point C?
