### Lesson 1: Reflection and Its Importance

Lesson 1 discusses the role of light to vision, the principle of the line of sight method of locating images, the law of reflection and the distinction between specular and diffuse reflection. Items in the group's pool include breathtaking photos of specular reflection and several other reflection phenomena such as the reflection of laser light, the use of periscopes, and much more. Photos complement many of the discussions from Lesson 1 of the Reflection and the Ray Model of Light chapter of The Physics Classroom Tutorial.

### Lesson 2: Image Formation in Plane Mirrors

Lesson 2 discusses why an image is formed, the characteristics of images formed by plane mirrors and multiple mirror systems and the use of ray diagrams to predict the location of images and the manner by which light travels from an object to they eye when viewing an image. Items in the group's pool include photos of periscopes, kaleidoscopes, multiple mirror systems, the reflection of laser light by mirrors, and much more. Photos complement many of the discussions from Lesson 2 of the Reflection and the Ray Model of Light chapter of The Physics Classroom Tutorial.

### Lesson 3: Concave Mirrors

Lesson 3 discusses the anatomy of a curved mirror and the formation of images by concave mirrors. The use of ray diagrams and the mirror equation to identify the characteristics of such images is emphasized. Items in the group's pool include photos of images formed by various mirrors (concave, convex, and funhouse mirrors), radio telescope dishes, and much more. Photos complement many of the discussions from Lesson 3 of the Reflection and the Ray Model of Light chapter of The Physics Classroom Tutorial.

### Lesson 4: Convex Mirrors

Lesson 4 discusses the formation of images by convex mirrors. The use of ray diagrams and the mirror equation to identify the characteristics of such images is emphasized. Items in the group's pool include many photos depicting the images formed by a variety of convex reflecting surfaces. Photos complement many of the discussions from Lesson 4 of the Reflection and the Ray Model of Light chapter of The Physics Classroom Tutorial.
