White light is spread out into its spectral components by a diffraction grating. If the grating has 2000 lines per centimetre, at what angle does red light of wavelength 685 nm appear in third order maximum.

The wavelengths of the visible spectrum are approximately 400nm (violet) to 700nm (red). Find the angular width of the first-order visible spectrum produced by a transmission diffraction grating with 405 lines per millimeter when white light falls normally on the grating.Give your answer in degrees.

Intense white light is incident on a diffraction grating that has 672 lines/mm. (a) What is the highest order in which the complete visible spectrum can be seen with this grating? (Enter 1 for first order, 2 for second order, etc.) (b) What is the angular separation between the violet edge (400 nm) and the red edge (700 nm) of the first order spectrum produced by the grating? O

You will view a source of white light through a diffraction grating that has 1000 lines/mm. (a) Find the angles that contain the visible spectrum at 1st order. (b) You can’t see the entire spectrum at 2nd order. What is the last wavelength that is visible, assuming you can see out to 90 degrees. What color is that?

Monochromatic red light with a wavelength of 660nm is incident on a pair of narrow slits that are separated by a distance of 4.00×10^4 *m. A viewing screen is placed a distance of 120cm behind the slits to observe the intensity pattern of the light after passing through the slits. a) Relative to the center of the pattern, where is the center of the third bright fringe?

A diffraction grating has a grating constant of 415 lines/mm. If composite light with wavelengths of 601 nm and 461 nm are incident upon the grating, what is there angular separation in the 1st order spectrum? Answer this with a positive number of degrees.

A single slit of width 4.50 x 10 ºm produces a first-order dark fringe at some angle. If the width of the slit is now changed to 3.08 × 10-ºm, a second-order dark fringe is found at three times the previous angle. What is the wavelength of the light?

Problem 10:   Consider a diffraction grating through which monochromatic light (of unknown wavelength) has a first-order maximum at 22°. At what angle, in degrees, does the diffraction grating produce a second-order maximum for the same light?

A thin film with an index of refraction of 1.50 is placed in one of the beams of a Michelson interferometer. If this causes a shift of 8 bright fringes in the pattern produced by light of wavelength 480 nm, what is the thickness of the film?
