Exam Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) A single slit forms a diffraction pattern, with the Frst minimum at an angle of 40° from central maximum. Monochromatic light of 450 - nm wavelength is used. The same slit, illuminated by a different monochromatic light source, produces a diffraction pattern with the second minimum at a 60° angle from the central maximum. The wavelength of this light, in nm, is closest to: A) 375 B) 357 C) 303 D) 321 E) 339 1) 2) A single slit forms a diffraction pattern, with the Frst minimum at an angle of 40° from central maximum. Monochromatic light of 640 - nm wavelength is used. The width of the slit, in nm, is closest to: A) 996 B) 914 C) 955 D) 873 E) 832 2) 3) A single slit, 2300 nm wide, forms a diffraction pattern when illuminated by monochromatic light of 460 - nm wavelength. The largest angle from the central maximum at which the intensity is zero is closest to: A) 84° B) 78° C) 81° D) 87° E) 90° 3) 4) A single slit, 1500 nm wide, forms a diffraction pattern when illuminated by monochromatic light of 620 - nm wavelength. At an angle of 10° from the central maximum, the phase angle between wavelets originating at the far edge of the slit, relative to wavelets originating at the near edge, is closest to: A) 2.0 rad B) 2.6 rad C) 1.3 rad D) 4.0 rad E) 3.3 rad 4) 5) A single slit, 2300 nm wide, forms a diffraction pattern when illuminated by monochromatic light of 660 - nm wavelength. At an angle of 10° from the central maximum, the ratio of the intensity to that of the central maximum is closest to: A) 0.33 B) 0.25 C) 0.41 D) 0.29 E) 0.37 5) 6) A single slit forms a diffraction pattern with monochromatic light. The 6th minimum of the pattern occurs at an angle of 23° from the central maximum. The number of bright bands on either side of the central band is closest to: A) 16 B) 13 C) 14 D) 15 E) 17 6) 7) A single slit forms a diffraction pattern with monochromatic light. The fourth minimum of the pattern occurs at an angle of 25° from the central maximum. The angle at which the Ffth minimum of the pattern occurs is closest to: A) 31.4° B) 32.9° C) 31.9° D) 32.4° E) 30.9° 7) 8) An 18 mm wide diffraction grating has rulings of 690 lines per mm. Light is incident normally on the grating. Monochromatic light of 554 nm wavelength is used. The largest angle from the normal at which an intensity maximum is formed is closest to: A) 50 B) 46 C) 48 D) 42 E) 44 8) 1
