Notes:Name: __________________________Cornell NotesOptics - ReflectionDirections: Fill in the blanks and boxes in the note panel. After notes are done, part of your homework is to fill in the sides with study questions and write a summary that demonstrates you understand what is important in the notes.Plane MirrorsQuestions/Main IdeasMain NotesSpeed of light = ______________________ or __________________in a vacuum! A plane mirror is a mirror that is ___________. They produce an image that is identical in size and orientation to the original._______________________1694180132715____________________________________________________________________________________________When light hits a mirror we refer to specific parts with these names:__________________: perpendicular line from surface of mirror__________________: light ray that strikes the mirror__________________: light ray that reflects off the mirror__________________: is measured between the incident ray and normal__________________:is measured between the reflected ray and normalLaws of Reflection:???1st LawDraw the ___________Measure the __________ angleDraw the reflected ray2nd Law 48260120269000To find an image: ____________ the _____________ ray behind the mirror.
