46 The figure below shows two diffraction patterns. The top one
was made with yellow light, and the bottom one with red. Could
the slits used to make the two patterns have been the same?47 The figure on p. 837 shows a diffraction pattern made by a
double slit, along with an image of a meter stick to show the scale.
The slits were 146 cm away from the screen on which the diffraction
pattern was projected. The spacing of the slits was 0.050 mm. What
was the wavelength of the light?√48 Why would blue or violet light be the best for microscopy?
.Solution, p. 105049 The figure below shows two diffraction patterns, both made
with the same wavelength of red light. (a) What type of slits made
the patterns? Is it a single slit, double slits, or something else?
Explain. (b) Compare the dimensions of the slits used to make the
top and bottom pattern. Give a numerical ratio, and state which
way the ratio is, i.e., which slit pattern was the larger one. Explain..Solution, p. 105050 When white light passes through a diffraction grating, what
is the smallest value ofmfor which the visible spectrum of orderm
overlaps the next one, of orderm+ 1? (The visible spectrum runs
from about 400 nm to about 700 nm.)838 Chapter 12 Optics
