Although we have discussed single-slit diffraction only for a slit, a similar result holds when light bends around a straight, thin object, such as a strand of hair. In that case, a is the width of the strand. From actual laboratory measurements on a human hair, it was found that when a beam of light of wavelength 634.2 nm was shone on a single strand of hair, and the diffracted light was viewed on a screen 1.35 m away, the first dark fringes on either side of the central bright spot were 5.40 cm apart.
How thick was this strand of hair?

) In the figure, a slit 0.30 mm wide is illuminated by light of wavelength 426 nm. A diffraction attern is seen on a screen 2.8 m from the slit. What is the linear distance on the screen between e first diffraction minima on either side of the central diffraction maximum? Answer: 8.0 mm 30) A thin beam of laser light of wavelength 514 nm passes through a diffraction grating having 3952 lines/cm. The resulting pattern is viewed on a...
A single-slit diffraction pattern (c24p28) A single-slit diffraction pattern is formed when light of = 587.0 nm is passed through a narrow slit.

A diffraction pattern forms when light passes through a single slit. The wavelength of the light is 570 nm. Determine the angle that locates the first dark fringe when the width of the slit is (a) 3.8 × 10-4 m and (b) 3.8 × 10-6 m.
When monochromatic light passes through a narrow slit it produces on a screen a diffraction pattern consisting of bright and dark fringes. The intensity of the bright fringes, I, as a function of can be calculated by: where Where is the light wave length and a is the width of the slit. Plot the relative intenstiy I / Imax as a function of for -20o <= <= 20o. Make one plot that contains three graphs for the cases a =...
