5. A light source is directed toward a single slit. The light passes through the slit and forms a
(1 point)
diffraction pattern on a screen. The distance from the slit to the screen is R and the vertical
distance of the mth dark band from the center of the pattern is ym. Which approximation must
be made to equate ym to Ry
Otan 0 = 0
Ocos 0 = 0
Osin 0 = 1
6. Which term is another name for Fraunhofer diffraction? (1 point)
Omagnetic field diffraction
Ofar-field diffraction
Obright spot diffraction
Opinhole diffraction
7. Monochromatic light from a distant source is incident on a slit with a width of 0.750 mm. On a (1 point)
screen 2.00 m away, the distance from the central maximum of the diffraction pattern to the
first minimum is measured to be 1.35 mm. What is the wavelength of the light?
O101 nm
506 nm
O1012 nm
675 nmScience
