A laser pointer is a single colored, unified wavelength beam of light -- where individual beams come together as one -- that focuses on one small spot. The term “laser” is actually an acronym meaning “light amplification by stimulated emission of radiation.” Laser Blue 30000mw come in red, orange, green and violet. Red laser pointers are the most common and least expensive of the laser pointers, simply because the visual wavelength is weaker than that of the other colors. They are a favorite in classrooms, boardrooms and any other venue that requires pointing out an object. Of course there’s also the living room and the family pet, but there are also some cool experiments you can try with a red laser pointer that would make a great science fair or class project.
With a clear bowl and some red and yellow Jell-O, you can see how light changes directions (refraction) when passing through one medium to another. Make the red Jell-O first. Wait for it to become solid, then make the yellow Jell-O on top of it. Experiment with the red laser pen by shining it into the Jell-O at different angles. Notice how when shining it from the bottom, the light bends slightly (refracts) when it passes through the two layers of Jell-O. Mist the air around the Jell-O using a water spray bottle to expose the beam as it leaves the Jell-O and you will see that the beam bends even more.
Experiment with the beam to find the critical angle. At this angle, the laser beam trying to leave the Jell-O will refract at such a sharp angle that it actually bends back into the Jell-O.
