• 10:22, 25 April 2022 Physdemo talk contribs created page Michelson Interferometer (Created page with "{{NewDemo|subject=Light and Optics|topic=Diffraction and Interference|file1=Interferometer.gif}} An incident laser beam encounters a beam splitter. The two subsequent beams bounce off of mirrors and then rejoin. Interference results from the path length difference of the two beams. There is also a compensation plate which acts to give both beams the same amount of travel through glass. The two beams will appear on the screen along with an unfortunate secondary reflectio...")

• 10:20, 25 April 2022 Physdemo talk contribs created page Newton's Rings (Created page with "{{NewDemo|subject=Light and Optics|topic=Diffraction and Interference|file1=NewtonRings.gif}} The Newton's Rings apparatus consists of a curved piece of glass held with its convex side against a flat piece of glass. The thin film of air trapped between causes interference patterns which can be changed by tightening or loosening the screws holding the apparatus together. The interference patterns are projected onto a screen by reflecting white light off of the Newton's R...")

The interference pattern, which is now large enough to see clearly, is projected onto a screen or wall. The bright spot at the center of the pattern, Poisson's spot, is the result of light waves being bent around the ball bearing. '''Location: ''' * Laser: Shelf M-2...")

• 10:05, 25 April 2022 Physdemo talk contribs created page Rainbox (Created page with "{{NewDemo|subject=Light and Optics|topic=Refraction and Dispersion|file1=Rainbow.gif}} A bright light source shoots a beam of light through a piece of white cardboard with a hole in it into a round flask filled with water. An index card or piece of cardboard is placed on the other side of the flask to block the main beam. The refracted light is dispersed by the water in the flask and forms a rainbow on the white cardboard background. '''Location: ''' * Light Source: Sh...")
• 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...")

Put on the overhead and pour mineral oil over the cat; the cat shape disappears and all that can be seen is the smile. '''Location: ''' * Shelf M-3 *")

• 10:02, 25 April 2022 Physdemo talk contribs created page Disappearing Test Tube (Created page with "{{NewDemo|subject=Light and Optics|topic=Refraction and Dispersion|file1=Disappearing.JPG}} Mineral oil and the material the test tube is made out of have a very similar index of refraction. When the test tube is placed in the mineral oil, as the oil fills the test tube, the tube "disappears." The demonstration usually used with this set-up is as follows: A test tube is placed in the mineral oil before the lecture. During the lecture, the lecturer smashes another test t...")

• 09:57, 25 April 2022 Physdemo talk contribs created page Liquid Light Pipe (Created page with "{{NewDemo|subject=Light and Optics|topic=Geometrical Optics|file1=LiquidLight.GIF}} A laser is positioned so its beam is pointing at a small hole in the side of a plastic container. When the stopper to the hole is removed and the water pours out in an arc, the laser light follows the path of the water. NOTE: use a few drops of milk in the water to make the beam show up.

Laser light going through a cylindrical lens reflects off the board and also goes through the lens. Angles of reflection and refraction can be observed, as well as total internal reflection. A white light line source, such as an old slide projector with a slit slide, can also be used as a light source. Approaching total...")
