PPT-9.2 Reflection and Mirrors

Essential Questions What Are the Kinds of Reflections What Types of Images Do Mirrors Produce What Are the Kinds of Reflection Light obeys the law of reflection The angle of the reflection equals the angle of incidence. Consequently the distance between the image and the mirror is equal to the distance between the mirror and the object Indeed simple trigonometry for the point 0 y where the ray is re64258ected o64256 the mirror gives us two equations tan tan 1 and A . luminous. object is one that produces light.. An . illuminated. object is one that reflects light.. Luminous Objects. Illuminated Objects. Luminous and Illuminated Objects. We see things because they . Measurements of the speed of light (c) . Index of refraction v. medium. = c/n. the bending of light – refraction . total internal reflection . Color (wavelength and frequency, c = . l. f. . Dispersion. MIRRORS. Concave Mirrors. A con. cave. mirror has a surface that curves inward like a “. cave. ” or a bowl.. It follows the law of reflection, however, when parallel light rays approach a curved surface and strike at different points on the curve, each ray will reflect at a slightly different direction. . Section 1 . Mirrors. A. . Light is necessary for eyes to see. 1. . Light waves spread in all directions from a light.. 2. . The brain interprets light waves as traveling in a straight line.. B. Plane mirror. How do eyeglasses correct your vision?. When you look in a mirror, where is the face you see?. In which ways is a cell phone camera similar to a human eye?. © 2014 Pearson Education, Inc.. Plane mirrors. 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.. Clear vs. Diffuse Reflection. Specular reflection: light reflected from smooth shiny surfaces. . In specular reflection the incoming and reflected angles are equal (. . =. . ’). Diffuse reflection: light is reflected from a rough textured surface. By: Delaney Sacra, Helena Haddad, Natalie Safe, and Ryan . Verbrugge. Mirrors & Reflections Part 1.

Light travels in straight “beams”. beams = the length, height, and width of light. Basic Properties. Light travels much faster than sound. Speed of light = 983,571,056 feet per second!. Light. Science. . . Success Criteria. Aim. I can use a mirror to reflect light and explain how mirrors work. . I can explain why mirrors are good reflectors.. I can use mirrors to reflect light onto different objects.. Geometric Optics. Understanding images and image formation, ray model of light, laws of reflection and refraction, and some simple geometry and trigonometry.
