Learning Outcome Draw a ray diagram to find the position, nature and size of the image produced by a concave and convex mirrors
Plane Mirrors Light from object reflects into eye Eye sees image back here Image is virtual and laterally inverted
Curved (Concave) Mirrors P = pole, pa = principal axis C = centre of curvature, c = radius of curvature F = Focal point or focus,f = focal length f = c / 2 C F P c pa f
Ray Diagrams Rule 1: An incident ray parallel to the pa is reflected back through the focal point. F
Ray Diagrams Rule 2: An incident ray that passes through the focal point on the way to the mirror is reflected back parallel to the pa. F
Ray Diagrams Rule 3: An incident ray headed towards the pole reflects back at an equal angle F P
All three combined allow you to find the image In this example the image is inverted, diminished and real F P object image
Concave Mirrors Concave (or converging) mirrors focus light at the focal point. F
Convex Mirrors Convex mirrors have a focal point behind the mirror. Convex (or diverging) mirrors spread the light rays apart so that they appear to have come from the focal point F
Ray Diagrams The same rules can be applied to convex mirrors… All convex mirror images are virtual. object image F

Reflection from Curved Mirrors. 2 Curved mirrors The centre of the mirror is called the pole. A line at right angles to this is called the principal axis.
The sign on the magnification is related to the orientation of the object and resulting image.

Mirrors Characteristics & Ray Diagrams. Plane Mirrors Plane Mirror = a flat, smooth surface that reflects light by regular reflection. Created by coating.
Curved Mirrors Chapter 14, Section 3 Pg
Sections 11.5 & There are three basic types of mirrors: plane, concave, and convex Light rays behave differently when they reflect from curved mirrors.
As light reaches the boundary between two media, its energy is partially reflected back and partially transmitted into the new medium. partially transmitted.
Code for diagrams Types of Lines: Solid Lines = Light Rays Dashed Lines = Virtual Rays Dotted Lines = Guide lines (not a ray) Colors: Blue = Incident Light.
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.

RAY DIAGRAMS Steps for drawing a plane mirror ray diagram: 1. A ray that strikes perpendicular to the mirror surface, reflects perpendicular to the mirror.
Curved Mirrors The most common type of curved mirror is a spherical mirror A spherical mirror has the shape of a section from the surface of a sphere.

Concave Mirrors Can Form Real Inverted Images. Topic4.4 (Pages ) TODAY WE WILL... Have a quick review about plane mirrors, and the terms of a concave.
Convex Mirrors LG: I can describe the uses on convex mirrors and draw ray diagrams involving convex mirrors.
Optics Can you believe what you see?. Optics Reflection: Light is retransmitted from or “bounces off” an object.
The amount of reflection depends on how different the media are.
Sec Review of Law: the angle of reflection is equal to the angle of incidence We use ray diagrams to show how light rays change direction when.
There are some mirrors that distort the reflected image. Cosmetic mirrors magnify things, and other mirrors make things look smaller.
Optics Lesson 4 Reflection In Curved Mirrors. Terminology Centre of curvature (C) – Middle of the “circle” Focus (focal point) (F) – Where reflected rays.
Spherical Mirrors Spherical mirror – a section of a sphere of radius R and with a center of curvature C R C Mirror.
Real or Virtual? Real images A real image is one which can be produced on a screen and is formed by rays that converge. Imaginary images A virtual image.

Spherical Mirrors – Learning Outcomes Recognise and use key words relating to mirrors. Centre of curvature Focus / focal point, focal length Pole.
Reflection Regular reflection occurs when parallel light rays strike a smooth surface and reflect in the same direction. Diffuse reflection occurs when.

Mirrors that are not flat are called curved mirrors. Depending on whether the reflective coating is on the inside or outside of the curve will decide.
Mirrors. Mirrors and Images (p 276) Light travels in straight lines, this is the reason shadows and images are produced (p 277) Real images are images.

Curved Mirrors Curved mirrors are like plane mirrors they too have smooth, shiny surfaces that reflect light. The surface can either curve in (concave)
