The law of reflection states that the angle of reflection equals a) the angle of refraction. b) the complement of the angle of incidence. c) the supplement of the angle of incidence. d) the angle of incidence. 3. When an object is farther from a concave mirror than focal point, the image is a) real and inverted b) virtual and correct. c) real and correct. d) perverted and inverted 4. the velocity of light varies from medium to medium. This fact is responsible for the phenomenon known as a) reflection. b) refraction. c) diffraction. d) dispersion. 5. When light passes from a more dense into a less dense medium, the light a) passes straight through. b) is bent towards the normal. v) is bent away from the normal. d) is bent away from surface. 6.
