Light Mirrors and Lenses (3379.0K) - McGraw-Hill Higher Education

Properties of Light1. Light waves can be absorbed, reflected, ortransmitted when they strike an object.2. The color of an object depends on thewavelengths of light reflected by theobject.Reflection and Mirrors1. Light reflected from the surface of an objectobeys the law of reflection—the angle ofincidence equals the angle of reflection.2. Concave mirrors cause light waves to converge,or meet. Convex mirrors cause lightwaves to diverge, or spread apart.Refraction and Lenses1. Light waves bend, or refract, when theychange speed in traveling from onemedium to another.2. A convex lens causes light waves to converge,and a concave lens causes light wavesto diverge.Using Mirrors and Lenses1. A compound microscope uses a convexobjective lens to form an enlarged imagethat is further enlarged by an eyepiece.2. A refracting telescope uses a large objectivelens and an eyepiece lens to form an imageof a distant object.3. A reflecting telescope uses a large concavemirror that gathers light and an eyepiecelens to form an image of a distant object.4. Cameras use a convex lens to form animage on light-sensitive film.Copy and complete the following concept map.Lightis anis reflected byis refracted bythat cantravel inthat canbethat canbeips.msscience.com/interactive_tutorCHAPTER STUDY GUIDE 575
