You can learn 34+ pages measuring the diameter of human hair by laser diffraction analysis in Doc format. 9the centre of diffraction pattern depends on the diameter of the hair. For quick reference there is a tool that electricians use in their tool box. In this STEM lab learn how to use a laser for measuring the tiniest things like the width of a human hair. Check also: measuring and measuring the diameter of human hair by laser diffraction The light commercial laser pointers emit on the other hand is the perfect wavelength to measure the size of a human hair using the same method outlined below.
Students can compare the width of the diffraction pattern for different hairs measured. The two laser sources both provided consistent estimates of the hair diameter of approximately 50 m.

This plate was positioned exactly perpendicular to the laser to ensure that the measurement of the diffraction pattern was not skewed by the angle from which the laser emitted.
The two laser sources both provided consistent estimates of the hair diameter of approximately 50 m. The diffraction pattern will be measured with digital calipers and this measurement will be taken from the center of the patterns brightest point to the edge of the patterns first dark patch in millimeters to the nearest sig fig. The width of a human hair sourced from a female elementary school student was measured by light diffraction using red and blue laser pointers. 26Human Hair via Two-Color Light Diffraction Cecilia R. Keep the laser and the distance D to the wall or screen the same. The low-power coherent light can cause damage to the sensitive retina and may lead to permanent eye damage.
