One way to measure the width of a narrow object is to examine its diffraction pattern. When laser light is shone on a long, thin object, such as a straightened strand of human hair, the resulting diffraction pattern has minima at the same angles as for a slit of the same width. If a laser of wavelength 632.8 nm directed onto a hair produces a diffraction pattern on a screen 3.60 m away and the width of the central maximum is 1.50 cm, what is the thickness of the hair? um

**Measuring the Width of a Narrow Object Using Diffraction Patterns** One way to measure the width of a narrow object is to examine its diffraction pattern. When laser light is shone on a long, thin object, such as a straightened strand of human hair, the resulting diffraction pattern has minima at the same angles as for a slit of the same width. If a laser of wavelength 632.8 nm is directed onto a hair and produces a diffraction pattern on a screen 3.60 m away, and the width of the central maximum is 1.50 cm, what is the thickness of the hair?
