PPT-Geometric Optics Mirrors, light, and image formation

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. Science Standards Science as Inquiry Physical Science Mathematics Standards Problem Solving Communication Connection ComputationEstimation Measurement As the angle between two mirrors is increased and decreased the number of reflected images increas 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. 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).. 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.. 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. Optics. Reflection:. Light is retransmitted from or “bounces off” an object. Optics. Law of Reflection:. The angle of incidence equals the angle of reflection.. Optics. Refraction. Light “bends” or changes its angle as it moves from one medium to another.. September. 27, 2013. François . Labaye. , Pr. . Ye. group . at. JILA, Boulder. francois.labaye@jila.colorado.edu. 2.

"Since, in practice, we normally cannot solve the full electron-nuclear problem,. 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 c=3.0*10. 8. m/s..
