Measurement of the size of a Red Blood Cell (Erythrocyte) We can use Babinet’s principle to make an interesting measurement of biological relevance. These droplets are so small that they bounce back before reaching any surface. laser wavelength 632.8 nm screen distance D 892 mm. Our results showed us that the diffraction of light can be beneficial to many of the practical aspects of science which we can list under, and. We built our setup to prove the theory behind measuring the diameter of the hair by using a laser beam. where a is the width for the hair, d is the slit spacing for CD/DVD, is the wavelength. Experiment Results: 5.Find the thickness of hair by using the second equation which is:a L/Xm. In this case, a droplet size below 10μm would be recommended. Helium-neon laser, a slide for hair, a CD, a DVD, a clamp. If we go one step further, to an SMT, electronics, or textile production, it would be considered a risk to add water at all. Otherwise the cows would get soaked instead of just cooled. However, for cooling of a barn with cows, for instance, a much smaller droplet size between 35 – 60 μm would be recommended. As you can imagine, there is a huge difference between the feeling of a 50 micron droplet and a 2 micron droplet.Įxamples of droplet size in different industriesįor a cleaning or cooling application, a larger droplet size between 200 – 1,200 μm would be advantageous as you need a lot of water pressure. The two laser sources both provided consistent estimates of the hair diameter of approximately 50 m.
