87 Questions for Chapter 33: Wave Optics

  1. A double slit is illuminated simultaneously with orange light of wavelength 620nm and light of an unknown wavelength. The m=4 bright fringe of the unknown wavelength overlaps the m=3 bright orange fringe. What is the unknown wavelength?

  2. FIGURE Q33.1 shows light waves passing through two closely spaced, narrow slits. The graph shows the intensity of light on a screen behind the slits. Reproduce these graph axes, including the zero and the tick marks locating the double-slit fringes, then draw a graph to show how the light-intensity pattern will appear if the right slit is blocked, allowing light to go through only the left slit. Explain your re

  3. Light of wavelength620nmilluminates a diffraction grating. The second-order maximum is at angle 39.5°. How many lines per millimeter does this grating have?

  4. A Michelson interferometer is set up to display constructive interference (a bright central spot in the fringe pattern of Figure) using light of wavelength l. If the wavelength is changed to λ/2, does the central spot remain bright, does the central spot become dark, or do the fringes disappear? Explain. Assume the fringes are viewed by a detector sensitive to both wave

  5. A diffraction grating produces a first-order maximum at an angle of 20.0°. What is the angle of the second-order maximum?

  6. A diffraction grating is illuminated simultaneously with red light of wavelength660nmand light of an unknown wavelength. The fifth-order maximum of the unknown wavelength exactly overlaps the third-order maximum of the red light. What is the unknown wavelength?

  7. The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656nm (red) and 486nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 500lines/mm, and the light is observed on a screen 1.50m behind the grating. What is the distance between the first-order red and blue frin

  8. A helium-neon laser (λ=633nm) illuminates a diffraction grating. The distance between the two m=1 bright fringes is 32cm on a screen 2.0m behind the grating. What is the spacing between slits of the grating?

  9. In a single-slit experiment, the slit width is 200 times the wavelength of the light. What is the width (inmm)of the central maximum on a screen 2.0m behind the slit?

  10. A helium-neon laser (λ=633nm)illuminates a single slit and is observed on a screen1.5mbehind the slit. The distance between the first and second minima in the diffraction pattern is 4.75mm. What is the width (inmm)of the slit?
