A grating spectrometer is used to resolve first order peaks from two wavelengths of ?1=555.00 nm and ?2=555.29 nm. What is the minimum number of slits this grating must have to resolve these wavelengths?
as we know resolving power
R = L / dL
for first order resolving power
1 * N = 555 / ( 555.29 - 555)
N = 1913.8
N ≈ 1914

A diffraction grating is used in second order, to resolve the spectrum of the light emitted by a sodium lamp. The sodium light is known to contain a doublet (λ 1 589.00 nm and λ2-589.59 nm). The grating contains 500 lines per centimeter. What is the minimum size of the grating that must be illuminated by the collimated light in order to resolve the two spectral lines?
Define briefly the resolution of a diffraction grating. Two spectral lines in a mixture of Hydrogen (H2) and Deuterium (D2) gas have wavelengths of 656.30 nm and 656.48 nm, respectively. What is the minimum number of lines a diffraction grating must have to resolve the two wavelengths in the third order maximum?
White light containing wavelengths from 410 nm to 750 nm falls on a grating with 7500 slits/cm. How wide is the first-order spectrum on a screen 3.90 m away?
Two of the lines of the atomic hydrogen spectrum have wavelengths of 656?nm and 410?nm. If these fall at normal incidence on a grating with 8200 slits/cm,what will be the angular separation of the two wavelengths in the first-order spectrum?
How many slits are needed in a diffraction grating that must resolve the m = 1 maxima of two spectral lines at lambda_s = 610 nm and lamd_1 = 615 nm? A 0.500-mu m-thick flake of glass (n_glass = 1.52) from a broken cover slip is floating on water (n_water = 1.33). If white light initially travelling in the air (n_air = 1.00) is incident normal to the surfact of the glass, what wavelengths in the visible spectrum undergo constructive...
A miniature spectrometer used for chemical analysis has a diffraction grating with 800 slits/mm set 25.0 mm in front of the detector "screen." The detector can barely distinguish two bright lines that are 30 μm apart in the first-order spectrum.

A beam of light consisting of two wavelengths, 546.0 nm and 409.5 nm, is used to illuminate two slits. The separation between the slits is 0.400 mm and the resulting interference patterns are observed on a screen that is 1.00 m from the slits. Calculate the minimum distance from the central maximum at which bright fringes from both patterns coincide
