Reflection and Refraction - UTSA
www.utsa.edureflection. Refraction The most common example of refraction is the bending of light on passing from air to a liquid, which causes submerged objects to appear displaced from their actual positions. Refraction is also the reason that prisms separate white light into its constituent colors. Refraction is commonly explained in terms

physics.fullerton.eduReflection and Refraction Physics 212 Lab . If the light is refracted as in . Figure 2, then 2 is defined as the angle of refraction. ( 1 is still the angle of incidence.) The amount that the ray of light will refract is related to the index of refraction of the medium. The index of refraction, n (no units), is defined as the ratio of the speed of light in a vacuum and the speed of light in the

vaga.studyIf light rays from an object, after reflection or refraction, actually meet at a point, then the image is called a real image. A real image is always inverted and can be obtained on a screen. If light rays from an object, after reflection or refraction, do not meet but appear to meet at a point, then the image is called a virtual image.
