Physics 1161 – Prelecture 23 Converging & Diverging Lenses.
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 Plane mirrors create virtual images. A virtual image is a point at which light rays appear to diverge without.
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.
Thin Lenses. Lens Types Converging Lenses Diverging Lenses f 1 : object focal point f 2 : image focal point.
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.
Ray Diagrams Noadswood Science, Ray Diagrams To be able to draw ray diagrams for converging and diverging lenses Thursday, December 03, 2015.
The sign on the magnification is related to the orientation of the object and resulting image.
8. Thin lenses Thin lenses are those whose thickness is small compared to their radius of curvature. They may be either converging or diverging. Example:
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.
As light reaches the boundary between two media, its energy is partially reflected back and partially transmitted into the new medium. partially transmitted.
Curved Mirrors Terminology center of curvature - C; the center of the original sphere radius of curvature - r; distance from center of curvature to.
Physics 014 Images. Topics Plane mirrors Spherical mirrors Thin lenses.
Light and Optics Mirrors and Lenses. Types of Mirrors Concave mirrors – curve inward and may produce real or virtual images. Convex mirrors – curve outward.
Geometric Optics: Mirrors and Lenses. Mirrors with convex and concave spherical surfaces. Note that θ r = θ i for each ray.

Ch. 18 Mirrors and Lenses Milbank High School. Sec Mirrors Objectives –Explain how concave, convex, and plane mirrors form images. –Locate images.
Optics Can you believe what you see?. Optics Reflection: Light is retransmitted from or “bounces off” an object.
Physics 1161 – Lecture 23 Lenses. Lens Equations convex: f > 0; concave: f < 0 d o > 0 if object on left of lens d i > 0 if image on right of lens otherwise.
SEEING THROUGH A LENS. We see the world through lenses. Eye glasses = lenses. Contact lenses = lenses. Magnifying glasses = lenses. Microscopes.
Refraction (bending light) Refraction is when light bends as it passes from one medium into another. When light traveling through air passes into the glass.
Principal axis FCC Image Characteristics Real Inverted f < d i < 2f h i < h o Any incident ray parallel to the principal axis will reflect through the.
Lenses Lenses _______ light and are usually used to form ________ There are two types: In practice, light is refracted at both surfaces of the lens but.
Curved Mirrors. Images in Mirrors S ize, A ttitude, L ocation, T ype Size –Is the image bigger, smaller or the same size as the object? Attitude –Is the.
