1. A light ray, traveling parallel to a converging mirro`r's axis, strikes the mirror's surface near its midpoint. After reflection, this ray travels A. parallel to the mirror's axis. B. at right angles to the mirror's axis. C. through the mirror's center of curvature. D. through the mirror's focal point. E. Not covered in the assigned reading. 2. White light is A. light of wavelength 550 nm, in the middle of the visible spectrum. B. a mixture of all visible frequencies. C. a mixture of red, green, and blue light. D. the term used to describe very bright light. E. the opposite (or complementary color) of black light. 3. If you stand in front of a diverging mirror, at the same distance from it as its radius of curvature, A. you won't see your image because there is none. B. you won't see your image because it's focused at a different distance. C. you will see your image and you will appear smaller. D. you will see your image and you will appear larger. E. you will see your image at your same height. 4. What color does blue pigment definitely subtract from white light? A. blue B. red C. violet D. green E. None of these. 5. When red light and green light shine on the same place on a piece of white paper, the spot appears to be A. yellow B. white C. brown D. black E. None of these. 6.
