1. Chapter 29 Reflection & Refraction May 16 – 23 Mr. Gaydos

2. Chapter 29 Notes I. Introduction: A. Reflection: Waves incident upon a surface, some or all of the energy bounces back. B. Refraction: Waves incident upon a medium, waves are bent as they enter & travel within the medium.

5. Mirror KPPs Plane (Flat Mirror) – Image same size as Object – Image orientation is ____________ relative to object – Image located same distance “behind” mirror as object is in front of mirror – More than one Plane mirror will result in multiple images

6. Mirror KPPs Concave mirror – Reflecting surface bent inwards away from object. – Image orientation is ____________ relative to object – Image location is ______________ relative to location of object. – Image size is _____________ relative to size of object.

7. Mirror KPPs Convex Mirror – Reflecting surface bent outwards towards object. – Image orientation is ____________ relative to object – Image location is ______________ relative to location of object. – Image size is _____________ relative to size of object
