Question

Two identical speakers are
situated in the x-y plane. Speaker_{1} has coordinates (0,
0) and speaker_{2} has coordinates (7/2, 0). The speakers
are driven by the same source of frequency 113 Hz, and the velocity
of sound is 339 m/sec. Find the location (in fractional form) of
all the minima and maxima for 0 < x < 7/2

Answer #1

position of minima is determined by

lambda is the wavelength which we can write as

c is speed of sound and nu is frequancy

so putting all values we get

so we get first mini,at n=1

for n=2

but it lays outside so exclude

and position of maxima

so putting value

so first maxima n=1

d=3

so only one maxima and one minima is in between 0<x<7/2

Two identical speakers are situated in the x-y plane.
Speaker1 has coordinates (0, 0) and speaker2
has coordinates (7/2, 0). The speakers are driven by the same
source of frequency 113 Hz, and the velocity of sound is 339 m/sec.

Two identical loudspeakers are situated at the same height above
a horizontal xy-plane and emit sound waves of frequency 1660 Hz.
The speakers are located at coordinates (0,1.57) and (0,-1.57),
with units in meters. A point O on the x-axis a distance
x1 = 9.1 meters away (x1,0) is the location
of an interference maximum. A second point P at (x1,
y2) is the location of the first minimum of sound
intensity when moving away from point O in the...

Two speakers emit identical sounds at a frequency of 793 Hz and
are placed 1.4 meters apart from each other. How far away from one
of the speakers should you stand so that the sound you hear is a
maximum? A minimum? How many maxima/minima are there? (You may
assume that you and the two speakers make a right triangle)

Imagine two identical speakers driven by the same source that
are 3.00m apart on the Y−axis, one being at the origin. The
listener is positioned on the X−axis, 5.00m in front of the speaker
at the origin. (a) Find the second lowest and third lowest
frequency for destructive interference (minimum signal) at the
listener’s location. (b) Find the lowest and the second lowest
frequency for constructive interference (maximum signal) at the
listener’s location. Draw any relevant diagrams.

A 4 x 10 cm rectangular loop of wire is situated on the x-y
plane with its corners located at coordinates (0, 0), (10,0), (10,
4) and (4,0) respectively. The loop has a current of 30 A flowing
in the counter-clockwise direction. Determine the magnetic field at
the centre of the loop.

c)
Find the moment velocity and acceleration at t = 2 seconds.
