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
