Study Notes

Reflection and Mirrors

Specular reflection is observed on smooth, shiny surfaces
Plane mirrors produce a virtual and upright image
The image orientation for a plane mirror image is upright and virtual

Lenses

Convex lenses converge light
Convex lenses refract light inward, toward the principal axis
The principal axis of a lens is an imaginary line passing through the center of the lens
The focal point of a lens is the point where parallel light rays converge

Mirror Image

The size and magnification of a mirror image are determined by the object's distance from the mirror
The type of image formed by a plane mirror is virtual and upright

Concave Mirrors

Concave mirrors diverge light
Concave mirrors refract light outward, away from the principal axis

Image Formation

The characteristics of an image formed by a lens are affected by the object's location
An object's location determines the real or virtual nature of the image formed by a lens
