Terms Plane mirror a smooth reflecting surface Virtual image images formed by a plane mirror CANNOT be projected onto a screen Real image images that can be projected onto a screen ie pin hole camera. 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 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. December 4. th. . REVIEW. What do you remember. ?. December 4. th. 2015 page 111. DO: I . will be able to explain the nature of waves, their behaviors and characteristics as they are manipulated by mirrors and lenses. Important vocabulary. Reflection- . the bouncing back of light from a surface.. Plane Mirror- . a mirror with a flat surface.. Concave Mirror- . a mirror that curves inwards in the middle. Convex Mirror- . Light rays and the laws of reflection help determine how and where an image is formed in a plane mirror.. REFLECTION is the bouncing back of light rays from a surface.. Using Light Rays to Locate an Image. Section 1 . Mirrors. A. . Light is necessary for eyes to see. 1. . Light waves spread in all directions from a light.. 2. . The brain interprets light waves as traveling in a straight line.. B. Plane mirror. 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.. Sound. Sound waves are compressional waves.. Two regions: compressions and rarefactions. Sound travels faster in liquids and solids than in gases.. Why? The molecules in liquids and solids are closer together.. 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.

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. 5.2 Using Mirrors to Form Images. All mirrors reflect light according to the . law of reflection. ..
