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
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.
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.
Textbook Reference 10.4 (P ). Convex Mirrors A mirror with a surface curved outward is a convex mirror, also called a diverging mirror A convex.
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.

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.

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.
