A diffraction grating consists of a large number of parallel, closely spaced slits. The number of lines/mm is indicated on the diffraction grating: 500 lines/mm. Determine the distance between the slits (d) in m. Show the calculations that your group has decided to be correct here and then indicate your value for d.

A diffraction experiment involving two thin parallel slits yields the pattern of closely spaced bright and dark fringes shown in the following figure. Only the central portion of the pattern is shown in the figure. The bright spots are equally spaced at d = 1.57 mm center to center (except for the missing spots) on a screen 2.15 m from the slits. The light source was a He-Ne laser producing a wavelength of 632.8 nm. (a) How far apart are...
A diffraction grating has exactly 9000 slits equally spaced across a total distance 1.10 cm. What is the distance between two neighboring slits? You send a single color of light through the grating of the previous problem and find a viewing angle of 28° for the m = 1 bright spot. What is the wavelength of this light?
If a diffraction grating has 13,000 slits in a distance of one inch, the distance d between adjacent slits (in mm) is about A) 0.001 B) 0.002 C) 0.004 D) 0.008
You send coherent 550 nm light through a diffraction grating that has slits of equal widths and constant separation between adjacent slits. You expect to see the fourth-order interference maximum at an angle of 66.6∘ with respect to the normal to the grating. However, that order is missing because 66.6∘ is also the angle for the third diffraction minimum (as measured from the central diffraction maximum) for each slit. a. Find the center-to-center distance between adjacent slits. b. Find the...
A metallic sheet has a large number of slits, 5.0 mm wide and 20 cm apart, and is used as a diffraction grating for microwaves. A wide parallel beam of microwaves is incident normally on the grating. In the situation above, the microwave wavelength is 6.0 cm. The largest angle from the normal, at which an intensity maximum occurs, is closest to: Situation A metallic sheet has a large number of slits, 5.0 mm wide and 20 cm apart, and...
