3. Categorize each statement as true or false. At the critical angle, no light is reflected and all light is transmitted. During refraction, the ray that travels through the second medium is called the incident ray. The angle of refraction is measured from the perpendicular to the boundary between two materials. The speed of light in a medium is always less than the speed of light in a vacuum. The virtual image of a pencil in a glass of water is closer to the viewer than the actual pencil. True False
