PPT-Light – Image formation, Mirrors, Properties

Light It is a form of Electromagnetic Energy Part of Electromagnetic spectrum and is the only part where we can see The speed of light C is constant in the vacuum Speed of light c3010 8 ms. Optics. is the study of the behavior and properties of light.. This includes it’s interactions with objects including mirrors, lenses, and substances which reflect or scatter light.. When Light Strikes an Object. Object . vs. Image. In this section we will be studying how mirrors and lenses will affect the way an object appears to us.. The thing that exists in the real world is referred to as the . object. .. 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. . 14.1: Mirrors. I. Plane Mirrors. Flat, smooth mirro. r. Creates a . virtual image. : an image your . brain. perceives even though . no light rays pass through it. .. Image appears . upright. and as far behind the mirror as the object is in front of it (same size as object).. 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. 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. 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. 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.. 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.. 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. Wavefronts. and Rays. In describing the . propagation of . light as a wave we need . to understand. :. wavefronts. : a surface . passing through . points of a wave . that have . the same phase . and amplitude. Mirrors. Recall that your eyes gather light reflected off of objects . This allows you to see the objects. Light can reflect more than once. Light bouncing off of you can then bounce off of a mirror. Section 1: Objectives. Use. ray diagrams to show how light is reflected or refracted.. . Compare . plane mirrors, concave mirrors, and convex mirrors.. . Use. ray diagrams to show how mirrors form images.. Geometric Optics. Understanding images and image formation, ray model of light, laws of reflection and refraction, and some simple geometry and trigonometry. The study of how light rays form images with optical instruments.
