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 Eye sees image back hereImage is virtual and laterally inverted Light from object reflects into eye
Curved (Concave) MirrorsF P c pa f P = pole , pa = principal axis C = centre of curvature, c = radius of curvature F = Focal point or focus, f = focal length f = c / 2
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 P F
All three combined allow you to find the image In this example the image is inverted, diminished and real object F P 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 F image
Mirror and Lens by Rifki Irawan. a surface, such as polished metal or glass coated with a metal film, that reflects light without diffusion and produces.
Mirror and Lens Properties. Image Properties/Characteristics Image Type: Real or Virtual Image Orientation: Erect or Inverted Image Size: Smaller, Larger,
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.
TODAY WE WILL... Practice how to draw the images in convex mirrors. Complete activity 4.10 “Trends in Images in Convex Mirrors”. SUCCESS CRITERIA - You.
TOC 1 Physics 212 and 222 Reflection and Mirrors What do we see? Law of Reflection Properties of Spherical Mirrors Ray Tracing Images and the Equations.

Chapter 13: Section 3. Learning Targets Describe the difference between a real and a virtual image Draw ray diagrams for objects located at various distances.
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.
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.
Reflection of Light. When light rays hit an object, they change direction. The type of surface the light encounters determines the type of reflection.

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.
LENS any transparent object having two nonparallel curved surfaces or one plane surface and one curved surface Converging Lenses - thicker in middle than.
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.
Curved Mirrors SNC2P – Optics. Curved Mirrors Curved mirrors are created when you make part of the surface of a sphere reflective There are two types.
