Textbook Question
Chapter 36, Problem 36.28E
The wavelength range of the visible spectrum is approximately 380-750 nm. White light falls at normal incidence on a diffraction grating that has 350 slits/mm. Find the angular width of the visible spectrum in (a) the first order and (b) the third order. (Note: An advantage of working in higher orders is the greater angular spread and better resolution. A disadvantage is the overlapping of different orders, as shown in Example 36.4.)

First-order Bragg scattering from a certain crystal occurs at an angle of incidence of
63.8°; see figure below. The wavelength of the x-rays is 0.261nm. Assuming that the
scattering is from the dashed planes shown, find the unit cell size ao.
63.8°
X rays
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.

Angel is experimenting with a diffraction grating of unknown spacing. He is looking to
determine the wavelength of the light in the emission spectrum of a gas and finds that a
light having a known wavelength of 602.4nm is deflected by 42.1 ° away from the
central maximum in the second order by this grating. Light of the wavelength to be
measured is deflected by 45.7° away from the central maximum in the second order.
What is the wavelength of this light in nanometers? Please give your answer as a whole
number.

- Diffraction 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?
