Images in Curved Mirrors all mirrors are not flat...

Can you think of examples of curved mirrors? Flashlights Makeup mirrors Security mirrors

2 Types of Curved Mirrors Concave Convex Pg 496

Concave Mirror Also known as a converging mirror Caves in Middle bulges away from you

Convex Mirror Also known as a diverging mirror Caves OUT Middle bulges TOWARDS you

Concave Mirrors Reflected rays always converge in a concave mirror This is why they are also called converging mirrors Pg 496

TERMS

Centre of Curvature (C) Centre of the sphere It is 2 times the length of the focus (F) Pg 496

Focus (F) A point where parallel light rays come together (converge) Pg 496

Principle Axis (P.A.) A line through the centre of curvature to the midpoint of the mirror Pg 496

Vertex (V) The point where the principle axis meets the mirror Pg 496

How to locate the Image in a Concave Mirror 1.From the top of the object, draw a light ray parallel to the P.A. When it hits the mirror, it should reflect through the focus

How to locate the Image in a Concave Mirror 2.From the top of the object, draw a light ray through the focus When it hits the mirror, it should reflect back, parallel to the P.A.

How to locate the Image in a Concave Mirror 3.Where the two light rays intersect (cross) that represents the top of the image Draw in your image

Try it out: Draw the focus 4 cm from the vertex. So this means C will be 8 cm from the vertex (2F). Find the reflected image.

 an image that is formed IN FRONT of the mirror  The image can be projected on a screen  an image that is formed BEHIND the mirror  The image CANNOT be projected on a screen
