Reflection Refraction
VocabularyVocabulary
Reflection: the bouncing of light from a Reflection: the bouncing of light from a surfacesurface
Refraction: the bending of light as it passes Refraction: the bending of light as it passes through one material to anotherthrough one material to another
Essential Knowledge, Skills, and ProcessesEssential Knowledge, Skills, and Processes
Design an investigation to determine what Design an investigation to determine what happens to light as it passes through a happens to light as it passes through a convex lens. Describe the results.convex lens. Describe the results.
A convex lens causes light to converge, or focus, producing an image that is smaller than the original object.
