This includes it’s interactions with objects including mirrors, lenses, and substances which reflect or scatter light.. When Light Strikes an Object. Unit 3:Light. Curved mirrors. Terms:. Curved mirror- can be thought of as a large number of plane mirrors all having slightly different angles. The laws of reflection still apply. Converging mirror- has a concave reflecting surface. The most common type of curved mirror is a spherical mirror. A spherical mirror has the shape of a section from the surface of a sphere. Curved Mirrors. Concave mirror – the inside surface of the mirror is polished. . How Do Your Eyes Help You See?. A lens is a curved surface, like a piece of glass or plastic.. Its curved shape makes light bend.. Lenses can make objects appear bigger or smaller to our eyes.. What is a lens?. Chapter 19. Reflection. The smooth surface of the lake reflects light rays so that the observer sees an inverted image of the landscape.. Law of Reflection. The law of reflection states that the angle of reflection is equal to the angle of incidence. . . How Do Your Eyes Help You See?. A lens is a curved surface, like a piece of glass or plastic.. Its curved shape makes light bend.. Lenses can make objects appear bigger or smaller to our eyes.. What is a lens?. Photo Terms. Focus is not an absolute. There is always a zone either side of the focused point that is acceptably sharp. The size of this zone will depend on how far away the subject is; the focal length and aperture of the lens; the size of the final picture; and what you regard as 'acceptable'. . S4P1 Students will investigate the nature of light using tools such as mirrors, lenses, and prisms. ..  . c. . Identify the physical attributes of a convex lens, a concave lens, and a prism and where each is used. . Sound. Sound waves are compressional waves.. Two regions: compressions and rarefactions. Sound travels faster in liquids and solids than in gases.. Why? The molecules in liquids and solids are closer together.. light bends or refracts when it moves from one medium to another. the light bends because it changes speed. if light slows down it bends toward the normal. if light speeds up it bends away from the normal. Matthew Mahek, OD. TTUHSC Department of Ophthalmology and Visual Sciences . Financial disclosures . . Objectives. Described a variety of uses for contact lenses. Discuss the complications associated with contact lenses. A Mirror
