Mirror and Lens Properties. Image Properties/Characteristics Image Type: Real or Virtual Image Orientation: Erect or Inverted Image Size: Smaller, Larger,
Lenses. Transparent material is capable of causing parallel rays to either converge or diverge depending upon its shape.

TOC 1 Physics 212 and 222 Reflection and Mirrors What do we see? Law of Reflection Properties of Spherical Mirrors Ray Tracing Images and the Equations.
Light and Optics Mirrors and Lenses. Types of Mirrors Concave mirrors – curve inward and may produce real or virtual images. Convex mirrors – curve outward.

Ch. 18 Mirrors and Lenses Milbank High School. Sec Mirrors Objectives –Explain how concave, convex, and plane mirrors form images. –Locate images.
CH 14: MIRRORS & LENSES 14.1: Mirrors. I. Plane Mirrors Flat, smooth mirror Creates a virtual image: an image your brain perceives even though no.
Lenses Physics 202 Professor Lee Carkner Lecture 21.
Refraction of Light EM lesson 8. Thicker in the center than at the edges Have positive focal lengths Converge parallel rays of light that pass through.
Refraction (bending light) Refraction is when light bends as it passes from one medium into another. When light traveling through air passes into the glass.
Physics 1161 – Prelecture 23 Converging & Diverging Lenses.
Optics Can you believe what you see?. Optics Reflection: Light is retransmitted from or “bounces off” an object.
Curved Mirrors Part 2 - Convex Mirrors. Review: Reflections in a Plane Mirror.
Concave/Convex Mirror Image Formation Rules 1.Parallel Rays - Light rays parallel to the principal axis are reflected through the focus of the mirror.
