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. 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. .. 14.1: Mirrors. I. Plane Mirrors. Flat, smooth mirro. r.

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. 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. It wasn’t until the early 19. th. century that light was theorized to behave as something other than a stream of particles.. Isaac Newton proposed the particle theory of light.. Newton’s theory was used to explain the reflection and refraction of light.. Light travels in a STRAIGHT LINE . ANOTHER WAY TO THINK OF LIGHT. Light leaving the candle travels in all directions, but we only SEE the light that travels in to our Eye-Brain. ANOTHER WAY TO THINK OF . 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.. OpenStax. Chapter . 25.
