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?

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?

(a) White light is spread out into its spectral components by a diffraction grating. If the grating has 2,070 grooves per centimeter, at what angle (in degrees) does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.)

The atomic emission spectrum of a light source is analyzed with a diffraction grating. A thick line near 589.0 nm is observed. In order to resolve the thick line into two fine lines in first order, you replace with a 2.450 cm long diffraction grating, and you barely observed two distinct first order spectral lines at 589.0 and 589.6 nm on a screen 5.000 m away. a. What is the resolving power of the grating? b. What is the slit...

A diffraction grating with 155 slits per centimeter is used to measure the wavelengths emitted by hydrogen gas. At what angles in the third-order spectrum would you expect to find the two violet lines of wavelength 434 nm and of wavelength 410 nm? (angles in radians) The 434 nm line: [5 points] 2 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] The 410 nm line:
