Exam 38: Diffraction Patterns and Polarization

A diffraction grating with 4000 lines/cm is illuminated by light from the sun.The solar spectrum is spread out on a white wall across the room.At what angle from the center line does blue light (400 nm)appear? At what angle from the center line does red light (650 nm)appear?

Light from a helium-neon laser (λ = 632.8 nm)is incident upon a 0.200-mm wide slit.Find the total width of the central maximum 2.00 m from the slit.

Each pattern shown below would appear on a screen when monochromatic light of wavelength λ first passes through a narrow slit of width a and then strikes a screen.The darkest areas on the page represent the brightest areas on the screen.In which case does the slit have the narrowest width?

When you look at a single slit diffraction pattern produced on a screen by light of a single wavelength,you see a bright central maximum and a number of maxima on either side,their intensity decreasing with distance from the central maximum.If the width of the slit is decreased,

A binary star system in the constellation Orion has an angular separation between the two stars of 1.2 × 10−⁵ radians.If λ = 5 × 10−⁷ m,what is the smallest aperture (diameter)telescope that may be used to resolve the two stars?

Jane's flashy boy friend has just given her a ring with a huge "diamond".Jane,who has studied physics,measures the polarizing angle for the stone and finds that the polarizing angle is 62.97°.The stone is

Monochromatic light from a He-Ne laser (λ = 632.8 nm)is incident on a diffraction grating containing 5000 lines/cm.Determine the angle of the first-order maximum.
