Mirrors why bother? . 3 types of mirrors. Flat (plane, infinite). Concave (caved in, converging). Convex (vexed out, diverging). Plane Mirrors. Is this kind of plane mirror possible?. Curved Mirror Terms. focal point= r/2 (horizontal light focuses here).

Is this kind of plane mirror possible?
focal point= r/2
(horizontal light focuses here)
The Center of Curvature or radius “r”
Real Image: Light from an object reflects off mirror, converges (focuses) back on same side of mirror(you see it and can feel it or re-project it)
Virtual Image: Light reflects off mirror but diverges (scatters) so it appears on the opposite side of mirror(you see it, but only in your mind- it’s not there!
object further than focal pt.
object closer than focal pt.
Object far from mirror: real, inverted, smaller
Object very close: virtual, upright, larger
No matter where you put the object,….
Only get……virtual, upright, smaller images
