White light is normally incident on a diffraction grating that has 6500 lines/cm. What is the angular separation Delta theta = theta_R - theta_V between red light (lambda = 700nm) and violet light (lambda = 400nm) in the first order (m = 1)?
(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.) (b) What If? What is the angular separation (in degrees) between the first-order maximum for 640 nm red light and the first-order maximum for green light of wavelength 525 nm? 11. (-/1...

White light is incident on a diffraction grating with 479 lines/mm. HINT (a) Calculate the angle θr2 (in degrees) to the second-order maximum for a wavelength of 620 nm. ° (b) Calculate the wavelength in nm of light with a third-order maximum at the same angle θr2. nm
28. When a narrow beam of white light is normally incident on a diffraction grating, you observe that the light to either side forms a complete spectrum from blue to red. Then you see that the spectrum repeats, but this time you see blue, then green, yellow, and purple, green, etc. The purple seems to be a mixture of red and blue light together. As you work through the problem, you conclude that blue light of wavelength 420 nm has...
If a diffraction grating produces a third-order bright spot for red light of wavelength 700 nm, at 65° from the central maximum at what angle will the second order bright spot be for violet light of wavelength 400 nm? How many lines per mm on this grating? If a diffraction grating produces a third-order bright spot for red light of wavelength 700 nm, at 65° from the central maximum at what angle will the second order bright spot be for...
