A diffraction grating with 4000 lines/cm is illuminated by light from the sun. The solar spectrum is spread out on a white wall across the room. (a) At what angle from the center line does blue light (400 nm) appear? (b) At what angle from the center line does red light (650 nm) appear? I know the formula that needs to be used is theta = m*wavelength/d but for the red light is sin theta = m*wavelength/d Thanks!
For a wavelength of 490 nm, a diffraction grating produces a bright fringe at an angle of 26°. For an unknown wavelength, the same grating produces a bright fringe at an angle of 36°. In both cases the bright fringes are of the same order m. What is the unknown wavelength? Bright fringe m (unknown wavelength) Bright fringe m (known wavelength) Central bright fringe (m- 0) Bright fringe m (known wavelength) Bright fringe m (unknown wavelength) Diffraction grating Screen
White light is passed through a diffraction grating that has 1 × 105 lines/m. On each side of the white central maximum, a spectrum of colors is observed. What is the wavelength of the light observed at an angle of 12.00° in the second-order bright fringes?
The light shining on a diffraction grating has a wavelength of 485 nm (in vacuum). The grating produces a second-order bright fringe whose position is defined by an angle of 8.09°. How many lines per centimeter does the grating have?
The light shining on a diffraction grating has a wavelength of 495 nm (in vacuum). The grating produces a second-order bright fringe whose position is defined by an angle of 9.34. How many lines per centimeter does the grating have?
The light shining on a diffraction grating has a wavelength of 481 nm (in vacuum). The grating produces a second-order bright fringe whose position is defined by an angle of 8.59°. How many lines per centimeter does the grating have?
Light of wavelength 429 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 × 10-5 m. The distance between the grating and the viewing screen is 0.10 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing). (a) Determine the distance y from the central bright fringe to the second-order bright fringe. (Hint: The diffraction angles are small enough that...

White light is spread out into its spectral components by a diffraction grating. If the grating has 1 970 grooves per centimeter, at what angle does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.) Mood Holn Bond It Montorit
