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...
Light of wavelength 385 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 0.18 m.

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
