You use a green laser (wavelength 532 nanometers) in order to measure the thickness of a hair. The formula for Diameter is lambda divided by the sine of theta. (but since theta is small we can use opposite over adjacent). x = 1.7 cm and d = 180 cm. What is the diameter (D)?

56329 x 10-9 meters
56.329 microns
56329 x10-7 meters
