The acoustical system shown in the figure below is driven by a speaker emitting sound of frequency 730 Hz. (Use v = 343 m/s.) If constructive interference occurs at a particular instant, by what minimum amount should the path length in the upper U-shaped tube be increased so that destructive interference occurs instead?m (b) What minimum increase in the original length of the upper tube will again result in constructive interference?
Point P is adistance of 8.5 m and 9.5 m from a speaker set. Both speakers emit identical sound waves with a wavelength of 1.0 m.a) If the waves are being emitted from both speakersin-phase, what kind of interference occurs at point P?b) What if the speakers emit waves out of phase by πradians? What interference would occur at P?
The analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. Two sources separated by 0.500 mm produce an interference pattern 525 cm away. The fifth and the second antinodal line on the same side of the pattern are separated by 98 mm. y= ________ d=________ m=_______ L=________
Two speakers, speakers 1 and 2, located 0.750 m apart from each other, are creating sound waves with an identical frequency of 686 Hz and are in phase. Assume the speed of sound in the room is 343 m/s. Your ear is directly in line with the speakers. a) Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location? b) You now go and stand directly in between the two speakers (0.375 m to the right of speaker 1 and 0.375 m to the left of speaker 2). Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location?

Explain in great detail, the two point source interference pattern and provide a diagram to further convey the concept.
Shown below is the central part of the interference pattern for a pure wavelength of red light projected onto a double slit. The pattern is actually a combination of singleand double-slit interference. Note that the bright spots are evenly spaced. Is this a double- or single-slit characteristic? Note that some of the bright spots are dim on either side of the center. Is this a single- or double-slit characteristic? Which is smaller, the slit width or the separation between slits? Explain your responses.
Two loudspeakers are placed above and below each other, as in the figure, and driven by the same spice at a frequency of 5.60* 10^2 Hz. An observer is in front of the speakers at point O, at the same distance from each speaker. What max vertical distance upward should the top speaker be moved to create destructive interference at point O? ( assume spread of sound is 343m/s)
A thin film of oil (n = 1.17) is located on smooth, wet pavement. When viewed from a direction perpendicular to the pavement, the film reflects most strongly red light at 640 nm and reflects no light at 512 nm. (b) Let m1 correspond to the order of the constructive interference and m2 to the order of destructive interference. Obtain a relationship between m1 and m2 that is consistent with the given data.
