mirrors and lenses

Plane Mirror

Forms virtual, erect images behind the mirror.

Concave Mirror

Reflecting surface is inward, converges light rays.

Focus

Point where converging rays meet in front.

Real Image

Can be projected on a screen, inverted.

Virtual Image

Cannot be projected, appears behind the mirror.

Convex Mirror

Reflecting surface is outward, diverges light rays.

Diverging Rays

Light rays spreading out after reflection.

Erect Image

Image orientation is the same as the object.

Concave Lens

Diverges light rays, forms virtual images.

Convex Lens

Converges light rays, forms real images.

Highly Diminished Image

Image much smaller than the object.

Magnified Image

Image larger than the object.

Inverted Image

Image orientation is opposite to the object.

Converging Lens

Brings parallel rays together at a point.

Diminished Image

Image smaller than the object but not highly.

Candle Placement

Close to lens creates magnified, erect image.

Far Off Object

Produces real, inverted, smaller image in mirrors.

Close Object

Produces virtual, erect image in concave mirrors.

Polished Surface

Smooth surface enhancing reflection quality.

Image Distance

Same as object distance for plane mirrors.

Image Characteristics

Depends on object distance from the mirror or lens.
