Properties of Curved Mirrors and Lenses
Converging Diverging F F
CONVERGING LENS Ray parallel to axis through F Ray through F parallel to axis
Ray through center of lensno bending
Diverging Lens – smaller virtual image inside of F
Mirror & Lens Equations

Si di M = -- = -- So do M = magnification Si = size of image So = size of object

Images formed by lenses. Convex (converging) lenses, f>0.
Mirror and Lens Properties. Image Properties/Characteristics Image Type: Real or Virtual Image Orientation: Erect or Inverted Image Size: Smaller, Larger,
Lenses Lenses do all the same things mirrors do and use all the same terms and variables. Lenses do all the same things mirrors do and use all the same.
Ray Diagrams for Lenses. Convex (Converging) Lenses There are two Focal points One in Front and one Behind Focal point is ½ way between Center of Curvature.
Plane Mirror: a mirror with a flat surface
Images Formed by Lenses Ray Diagrams for Lenses Ray diagrams can be used to predict characteristics of images using 3 rays, just like for concave.
Lenses. Transparent material is capable of causing parallel rays to either converge or diverge depending upon its shape.
Lenses Physics Mrs. Coyle. What phenomenon is evident in lenses? https://wiki.brown.edu/confluence/display/PhysicsLabs/PHYS+0080+BC.
Mirrors. Types of mirror There are two types of mirror Plane (flat) Curved Concave (curves in) Convex (curves out)
Thin Lenses. Two Types of Lenses Converging – Thicker in the middle than on the edges FOCAL LENGTH (+) POSITIVE Produces both real and virtual images.

8. Thin lenses Thin lenses are those whose thickness is small compared to their radius of curvature. They may be either converging or diverging. 1) Types.
How Does a Lens Work? Light travels slower in the lens material than in the air around it. This means a linear light wave will be bent by the lens due.

Light and Optics Mirrors and Lenses. Types of Mirrors Concave mirrors – curve inward and may produce real or virtual images. Convex mirrors – curve outward.
