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 which ranges between 170-10 microns. in that case, a is the width of the hair strand. from actual laboratory measurements on a human hair, it was found that when a beam of light of wavelength 523.3 nm was shone on a single strand of hair, and the diffracted light was viewed on a screen 2.55 m away, the strand of hair was 1.50x10-5 m in thickness. what was the spacing between the first dark fringe on either side of the bright spot?
