Chapter 35, Problem 4PQ
You are seated on a couch equidistant between two speakers. The speakers are 2.0 m apart and you are seated 4.0 m away from the point between the speakers as shown in Figure P35.4. Both speakers play an A note (a constant frequency of 440 Hz) in phase and at the same volume. As you move left and right along the couch, you notice that the volume alternates between minimum and maximum due to interference effects. Assume the speed of sound is 343 m/s.
- a. When you are seated at the center of the couch, is the sound a maximum or minimum in volume?
- b. If you slide along the couch to the left or right, approximately how far do you need to move until you reach the next location that has the same volume? (Hint: You may wish to obtain an exact expression and then use a spreadsheet or trial and error to find an approximate solution.)

Two identical audio speakers connected to the same amplifier produce in-phase sound waves with a single frequency that can be varied between 340 and 575 HzHz . The speed of sound is 340 m/sm/s . You find that where you are standing, you hear minimum-intensity sound
If one of the speakers is moved 39.8 cmcm toward you, the sound you hear has maximum intensity. What is the frequency of the sound?
Express your answer in hertz.
How much closer to you from the position in part B must the speaker be moved to the next position where you hear maximum intensity?
Express your answer in meters.
The figure shows a loud speaker A and point C where a listener is. AC= 1m and the angle is 40 degrees. B is somewhere to the left of A. Both speakers are playing out of phase a 65Hz tone. What is the second closest distance to speaker A that speaker B can be located so that the listener hears no sound?
In your summer internship at an optical products company, you need to measure the wavelength λ of the light that is produced by a laser. To do this, you pass the light from the laser through two narrow slits that are separated by a distance d. You observe the interference pattern on a screen that is 0.900 m from the slits and measure the separation Δy between the adjacent bright bangs in the part of the picture that is near the center of the screen Using a microscope, you measure d. However, both Δy and d are small and difficult to measure accurately, so you repeat the measurements for several pairs of slits, each with a different value of d. Your results appear in Figure P35.52, where you have plotted Δy as a function of 1/d. The line on the graph is the best straight line for the data. (a)Explain why data points drawn in this way are close to a straight line. (b) Use Figure P35.52 to calculate λ.

- The figure below shows a radio-wave transmitter and a receiver, both h = 57.0 m above the ground and d = 670 m apart. The receiver can receive signals directly from the transmitter and indirectly from signals that bounce off the ground. Transmitter Receiver (a) If the ground is level between the transmitter and receiver and a 1/2 phase shift occurs upon reflection, determine the longest wavelengths that interfere constructively. m (b) If the ground is level between the transmitter and receiver and a 1/2 phase shift occurs upon reflection, determine the longest wavelengths that interfere destructively. marrow_forwardA square is 3.80 m on a side, and point A is the midpoint of one of the sides. On the side opposite this spot, two in-phase loudspeakers are located at adjacent corners, as shown in the figure. Standing at point A, you hear a loud sound because constructive interference occurs between the identical sound waves coming from the speakers. As you walk along the side of the square toward either empty corner, the loudness diminishes gradually but does not entirely disappear until you reach either empty corner, where you hear no sound at all. Thus, at each empty corner destructive interference occurs. Find the wavelength of the sound waves. Number i Unitsarrow_forwardAn acoustic double-slit system (of slit separation d and slit width a) is driven by two loudspeakers . By use of a variable delay line, the phase of one of the speakers may be varied relative to the other speaker. Describe in detail what changes occur in the double-slit diffraction pattern at large distances as the phase difference between the speakers is varied from zero to 2p. Take both interference and diffraction effects into account.arrow_forward
- A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.arrow_forward35.

The receiver can receive sig- nals both directly from the transmitter and indirectly from signals that reflect from the ground. Assume the ground is level between the transmitter and receiver and a 180° phase shift occurs upon reflection.

In the interference pattern on the screen, what is the distance between the central bright fringe and the first bright fringe next to it (in m)?arrow_forwardIn your summer job at an optics company, you are asked to measure the wavelength λ of the light that is produced by a laser. To do so, you pass the laser light through two narrow slits that are separated by a distance d. You observe the interference pattern on a screen that is 0.900 m from the slits and measure the separation ∆y between adjacent bright fringes in the portion of the pattern that is near the center of the screen. Using a microscope, you measure d. But both ∆y and d are small and difficult to measure accurately, so you repeat the measurements for several pairs of slits, each with a different value of d. Your results are shown in Fig. P35.50, where you have plotted ∆y versus 1/d. The line in the graph is the best-fit straight line for the data. (a) Explain why the data points plotted this way fall close to a straight line. (b) Use Fig. to calculate λ.arrow_forward
- 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=________arrow_forwardearrow_forwardA double-slit interference pattern is observed on a screen with the intensity graph. Points A, B, C, D, and E are bright fringes. Points F, G, H, I, J, and K are dark fringes. The wavelength of the green light is 560 nm. The distance between the two slits is 0.40 mm, and the distance between the screen and the slit is 2.0 m. What is the distance between fringes C and B, in mm? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive.
