• 10:04, 25 April 2022 Physdemo talk contribs created page Bouncing Laser (Created page with "{{NewDemo|subject=Light and Optics|topic=Refraction and Dispersion|file1=bouncing_laser.jpg}} A 1:1 solution of Karo syrup and water is left to sit overnight. The syrup slowly sinks to the bottom and a varying level of index of refraction results. About 2 inches of syrup on the bottom looks good for this demo. A laser is shined into one end of the plexiglass tank, and it is seen to bend because of the varying index of refraction from the bottom to the top layer. When th...")
