Textbook Question
Chapter 26, Problem 6MCP
A laser beam of wavelength 500 nm is shone through two different diffraction gratings A and B, and the pattern is viewed on a distant screen. The pattern from grating A consists of many closely spaced bright dots, while that from B contains few dots spaced widely apart. What can you conclude about the line densities NA and NB (the number of lines/cm) of these two gratings?
- A. NA > NB.
- B. NA < NB.
- C. You cannot conclude anything about the line densities without knowing the order of the bright spots.

1. a. If a piece of glass (n = 1.5) is coated with a transparent plastic (n = 2.0), will there be a
phase shift in either of the beams reflecting off the interfaces (air/plastic and plastic/glass)? How
can you tell, without doing the experiment, whether or not there will be a phase shift in either
beam? Be specific about what rays are reflecting off what materials.
b. So what thickness or thicknesses give the maximum reflection? What thickness or thicknesses
(hint: it's thicknesses) give the minimum reflection? Assume that a light of wavelength 500. nm
is used, and you may leave the answer in nm. Yes, this is a choice between equations 35.17 and
35.18, but your answer to part a should be helpful in deciding which set.
You measure three segments of the distance between a diffraction slit an the screen on which the pattern forms: x1 = (15.8 ± 0.2) cm, x2 = (6.7 ± 0.1) cm, and x3 = (11.3 ± 0.1). What is the uncertainty of the total distance x1 + x2 + x3?

- X-rays incident on a crystal with planes of atoms located 0.378 nm apart produce a diffraction pattern in which a first-order maximum is observed at an angle of 14.2. a. What is the wavelength of the X-rays incident on the crystal? b. How many orders are visible in the diffraction pattern?arrow_forwardWhen 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. Figure 1 of 1 d sine d sine Review nstants Part A An x-ray beam with wavelength 0.260 nm is directed at a crystal.

Explain. C. How thick is the human hair strand used in the experiment?arrow_forwardDiffraction can be used to provide a quick test of the size of red blood cells. Blood is smeared onto a slide, and a laser shines through the slide. The size of the cells is very consistent, so the multiple diffraction patterns overlap and produce an overall pattern that is similar to what a single cell would produce. Ideally, the diameter of a red blood cell should be between 7.5 and 8.0 μm. If a 633 nm laser shines through a slide and produces a pattern on a screen 24.0 cm distant, what range of sizes of the central maximum should be expected? Values outside this range might indicate a health concern and warrant further study.arrow_forward9. A diffraction grating is placed 1.00 m from a viewing screen.
