e I e ) If a diffraction grating produces a sixth-order maximum for the shortest wavelength of visible light at 27.6, at what angle (in degrees) will the sixth- order maximum be for the longest wavelength of visible light? (Assume the wavelengths of visible light range from 380 nm to 760 nm in a vacuum.) L r _'_ At what angle is the first minimum for 550 nm light falling on a single slit of width 2.00 pm? - F
