Mirrors and Reflection

-Terminology-drawing images in mirrors

Plane Mirror:◦ A planar reflecting surface

Virtual Image◦ Image formed by light reflecting off of a mirror

Terms- Review

a) The image is located as far behind the mirror as the object forming it is in front of the mirror (distance (di) from the image to the mirror is equal to the distance (do) from the object to the mirror di= -do

Characteristics of Plane Mirrors

b) The image (Hi) is the same size as the object (Ho)- magnification =+1

Hi=Ho

Magnification (m)=Height of image (Hi) = - distance of image (di)height of object (Ho) distance of object (do)

m= Hi = - di Ho do

Plane mirror equation

c) the image formed is upright but laterally inverted

4 characteristics to consider:◦ Magnification◦ Attitude (upright or inverted)◦ Type (real or virtual)◦ Position

Drawing Ray Diagrams of Plane Mirrors

Labs:◦ Reflecting light off a plane mirror◦ Viewing images in a plane mirror

Plane mirror races??
