A common object, which is often used when referring to small things, is a human hair. Using the concept of diffraction, we will measure how thick a human hair actually is. Section One: Measuring a HairExperiment 13: Interference and Diffraction OBJECTIVES 1. To explore the diffraction of light through a variety of apertures using a laser pointer. 2. To measure the wavelength of the laser light; the spacing between the tracks of an audio compact disk (CD); and the thickness of a human hair. WARNING!
☛ Observe the diffraction pattern and compare it to the one obtained by the single slit. ☛ Measure the distance between minima of pattern, and determine the thickness of your hair. Experiment: Place component with double-slits into laser beam and observe diffraction pattern (youIn this video lesson, students will be introduced to the concepts of refraction, diffraction and the wave properties of light with examples. We then show an.In this experiment, we used a laser to discover how interference and diffraction work. We can use diffraction to accurately measure very small objects, like the spacing between tracks on a CD, the size of bacteria, and also the thickness of human hair. Here’s what you need: a strand of hair; laser pointer; tape; calculator; ruler; paper .
It is often necessary to measure the diameter of fine wire, hair, yarn or filament. The diffraction of laser light has been used in industry to measure the thic. . T. Kallard, 1977.

hair thickness d = λ / 0.0054 = 0.117 mm. Measurement of the size of a Red Blood Cell (Erythrocyte) We can use Babinet’s principle to make an interesting measurement of biological relevance. As we know, blood is made up of a liquid part – plasma – and a corpuscular part made up of the cells contained in the blood.
This is your mounting bracket. 2) Select one strand of hair approximately 15-25cm long. This hair needs to be mounted on the mounting bracket from step 1. 3) Mount the hair on the bracket using tape. Place the hair so that it bisects the mounting bracket. Make sure the hair is taut and straight. 4) Set the laser pointer (or laser) on the lab table.
