A student is doing a lab experiment in which she uses diffraction to measure the width of a shaft of her hair. She shines a 530 nm green laser pointer on a single hair, which produces a diffraction pattern on a screen 1.2 m away. The width of the central maximum of the pattern is 14 mm.a. What is the thickness of the hair?b. If she chose a wider shaft of hair, how would this change the width of the central maximum?
1. a. If a piece of glass (n = 1.5) is coated with a transparent plastic (n = 2.0), will there be a
phase shift in either of the beams reflecting off the interfaces (air/plastic and plastic/glass)? How
can you tell, without doing the experiment, whether or not there will be a phase shift in either
beam? Be specific about what rays are reflecting off what materials.
b. So what thickness or thicknesses give the maximum reflection? What thickness or thicknesses
(hint: it's thicknesses) give the minimum reflection? Assume that a light of wavelength 500. nm
is used, and you may leave the answer in nm. Yes, this is a choice between equations 35.17 and
35.18, but your answer to part a should be helpful in deciding which set.
The thickness of a human hair was measured using diffraction. A green laser (λ = 532 nm) was used
and the viewing screen was placed 1 m away from the slit plate. The table below shows the data
gathered for m = ±1.
