A Laser, or Light Amplification by Stimulated Emission of Radiation, has a high degree of spatial coherence. A high degree of spatial coherence means that the light that is being emitted from the laser is very concentrated making the visible distance that light is traveling much further than that of a standard light source. Another important property of lasers is that they only produce light from a single wavelength. The different wavelengths of light produced from the laser travel at different speeds making some colored lasers have a greater visible distance which they travel. Due to the laser's unique properties, it has gained significant popularity in various fields of science and the military. In the scientific applications, such as lunar laser ranging, the laser is required to travel from one medium to another, thus causing light refraction This light refraction can be accounted for if the index of refraction is known for both mediums and the incident angle. If a scientific experiment that used a laser, whose light was traveling through different mediums, was to switch their color of laser then their measurements would be different. This would happen because the different frequencies of the lasers which were used. In our experiment, we tested two different colored lasers, red and green, and the amount of refraction they have when their light travels from air to gelatin. In this experiment we hope to show how the different frequencies of lasers travel at different velocities.
