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.

Light and Optics Mirrors and Lenses. Types of Mirrors Concave mirrors – curve inward and may produce real or virtual images. Convex mirrors – curve outward.

Mirrors and Lenses: Mirrors reflect the light Lenses refract the light.

Curved Mirrors. Two types of curved mirrors 1. Concave mirrors – inwardly curved inner surface that converges incoming light rays. 2. Convex Mirrors –

Refraction of Light EM lesson 8.  Thicker in the center than at the edges  Have positive focal lengths  Converge parallel rays of light that pass through.

SEEING THROUGH A LENS.  We see the world through lenses.  Eye glasses = lenses. Contact lenses = lenses.  Magnifying glasses = lenses. Microscopes.

Today’s agenda: Death Rays. You must know when to run from Death Rays. Refraction at Spherical Surfaces. You must be able to calculate properties of images.

Ray Diagrams for Lenses. Convex (Converging) Lenses There are two Focal points One in Front and one Behind Focal point is ½ way between Center of Curvature.

Image Formation. Flat Mirrors  p is called the object distance  q is called the image distance  θ 1 = θ 2 Virtual Image: formed when light rays do.

LENSES Write down anything like this!.  Different types of lenses play an important part in our lives. They are used in cameras, telescopes, microscopes,

Lenses Lenses do all the same things mirrors do and use all the same terms and variables. Lenses do all the same things mirrors do and use all the same.

Lenses Lenses _______ light and are usually used to form ________ There are two types: In practice, light is refracted at both surfaces of the lens but.

Converging lens

We still draw our 2 lines We now have a reference line through middle of lense

Convergent means they will come together continue line rules

Draw your image

What trend is there?

Memorize this. For converging lenses: Behind f = real At f = no image In front of f = virtual Also called Convex Can produce real and virtual Can be upright or inverted Can be larger or smaller

Diverging lens

Memorize this. Also called concave Always virtual Always upright Always reduced Always on objects side of the lens
