Chapter 26, Problem 59GP
A physics student performs Young’s double-slit experiment with a collection of slits of varying separations He illuminates each in turn with laser light of unknown wavelength and measures the horizontal distance between the central bright fringe and the m = 3 bright fringe on a screen that is 2 m away. His measurements are given in the table
| Slit separation (mm) | y (mm) |
| 0.20 | 13.2 |
| 0.15 | 17.7 |
| 0.10 | 26.5 |
| 0.07 | 37.9 |
| 0.05 | 53.0 |
Make a plot of the fringe separation as a function of the inverse slit separation. Using a linear “best fit” to the data, determine the wavelength of the laser in units of nm.

When an x-ray beam is scattered off the planes of a
crystal, the scattered beam creates an interference
pattern. This phenomenon is called Bragg scattering. For
an observer to measure an interference maximum, two
conditions have to be satisfied:
1. The angle of incidence has to be equal to
the angle of reflection.
2. The difference in the beam's path from a
source to an observer for neighboring
planes has to be equal to an integer
multiple of the wavelength; that is,
2d sin(0) = mx for m = 1, 2, ....
The path difference 2d sin(0) can be determined from
the diagram (Figure 1). The second condition is known as
the Bragg condition.

- Youngs double-slit experiment underlies the instrument landing system used to guide aircraft to safe landings at some airports when the visibility is poor. Although real systems are more complicated than the example described here, they operate on the same principles. A pilot is trying to align her plane with a runway as suggested in Figure P27.2. Two radio antennas (the black dots in the figure) are positioned adjacent to the runway, separated by d = 40.0 m. The antennas broadcast unmodulated coherent radio waves at 30.0 MHz. The red lines in Figure P27.2 represent paths along which maxima in the interference pattern of the radio waves exist. (a) Find the wavelength of the waves. The pilot locks onto the strong signal radiated along an interference maximum and steers the plane to keep the received signal strong. If she has found the central maximum, the plane will have precisely the correct heading to land when it reaches the runway as exhibited by plane A. (b) What If? Suppose the plane is flying along the first side maximum instead as is the case for plane B. How far to the side of the runway centerline will the plane be when it is 2.00 km from the antennas, measured along its direction of travel? (c) It is possible to tell the pilot that she is on the wrong maximum by sending out two signals from each antenna and equipping the aircraft with a two-channel receiver. The ratio of the two frequencies must not be the ratio of small integers (such as 34). Explain how this two-frequency system would work and why it would not necessarily work if the frequencies were related by an integer ratio.arrow_forwardif the distance between the slits is doubled in Youngs experiment, what happens to the width of the central maximum?
