Chapter 33, Problem 42EAP
Because sound is a wave, it’s possible to make a diffraction grating for sound from a large board of sound-absorbing material with several parallel slits cut for sound to go through. When 10 kHz sound waves pass through such a grating, listeners 10 m from the grating report “loud spots” 1.4 m on both sides of center. What is the spacing between the slits? Use 340 m/s for the speed of sound.

- A radio telescope consists of two antennae separated by a distance of 235 m. Both antennae are tuned to 26 MHz. The signals from the two antennae are fed into a common amplifier, but one signal is passed through a phase adjuster that delays the phase by a chosen amount, 6, so that the telescope effectively "looks" in different directions. When 8=0, plane radio waves that are incident vertically on the antennae produce signals that add constructively at the amplifier. What is the minimum phase delay that should be introduced in order that signals coming from an angle 0 = 18 degrees from the vertical will add constructively at the amplifier? Give your answer as a positive number in radians, and use 3 x 108 m/s for the speed of light.

- 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.arrow_forwardThe table contains data obtained during the single-slit microwave experiment with a slit width of 7 cm and a wavelength of 2.8 cm.

- Your physics study partner tells you that the width of the central bright band in a single-slit diffraction pattern is inversely proportional to the width of the slit. This means that the width of the central maximum increases when the width of the slit decreases. The claim seems counterintuitive to you, so you make measurements to test it. You shine monochromatic laser light with wavelength λ onto a very narrow slit of width a and measure the width w of the central maximum in the diffraction pattern that is produced on a screen 1.50 m from the slit. (By “width,” you mean the distance on the screen between the two minima on either side of the central maximum.) Your measurements are given in the table. (a) If w is inversely proportional to a, then the product aw is constant, independent of a. For the data in the table, graph aw versus a. Explain why aw is not constant for smaller values of a.

- The interference figure of a set of double slits is measured on a screen. The experiment is carried out with a laser with a wavelength of 450 nm (approach the speed of light to 300,000 km/s in this situation) and it is measured that the interference maximum m=2 is 10 mm away from the main maximum. Then 2 pieces of glass are placed in front of each of the slits. The piece of glass P1 causes a delay in the wave (relative to a wave traveling in air) of 7.5 10^(-16) s. The piece of glass P2 causes a delay of 3.75 10^(-16) s. How many mm will the main maximum be shifted from the initial position?arrow_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_forwardAlthough beats are often associated with sound waves, light waves can also exhibit beats, in which case it is brightness instead of loudness that changes with time. To test this, you perform the double slit experiment with a laser that emits two different wavelengths of light, 450 nm (blue) and 650 nm (red). Both wavelengths are sent through both slits. The slits are separated by 7.5 × 10−5 m and the interference pattern is observed on a screen located 1.5 m away from the slits. All light rays have the same phase constant. a) What wavelength of light do you see at the center of the screen and what is the time interval between moments of maximum brightness? b) Consider the first location above the center at which the red light constructively interferes. Between the center and this location, how many times will the blue light destructively interfere? How about constructively interfere? c) Determine the smallest distance from the center of the screen to the location where both the red…arrow_forward
