Yesterday’s Review
0Law of reflection is: the angle of incidence is equal to the angle of reflection, or, θi = θr
0Plane mirror characteristics:0 Object size = image size0 Object distance = image distance0 Always forms a virtual image (the image cannot be
projected onto a screen)0 Image is reversed

Yesterday’s Review
0Plane mirror drawings:0 How did you draw the images in the plane mirror
from yesterday?0 Question 7 – How is it done?

Goals for the day
0Be able to draw a ray diagram for a concave mirror0Know the location & orientation (right side up or
upside down) of images in concave mirrors0Be able to communicate using appropriate
terminology such as: angle of incidence, angle of reflection, normal, centre of curvature, focus, & principal axis

Curved Mirror Terminology
0Center of curvature (C): the center of the circle where the mirror represents a small arc
0Focus (F): the point where parallel light rays converge; the focus is always found midway between the point where the principal axis cross the mirror
0Principal axis (PA): a line drawn through the center of curvature, the focus, and the mirror upon which the object rests

Characteristics of Concave Mirrors
0Concave mirror characteristics can differ depending on where the image is located in comparison to C and F
0L.O.S.T. can be used to remember what characteristics to look for:0 L is for relative location0 O is for orientation (upright or upside down)0 S is for the relative size of the image to the object
(bigger, smaller, or same size as the object)0 T is for type of image (either real or virtual)
