Physics Presentation Lenses What are lenses? Diverging Lens Diverging Lens Converging Lens Converging or Diverging? Image formation by Lens Lenses are made from transparent
glass or plastic

Used to magnify images or projects images into a screen

Can be shaped and polished to control how the light rays CONVERGE and DIVERGE
Thinner at the center , thicker at
the edges a parallel beam of light passing through it is caused to diverge or spread out. Thicker at the center , thinner at the edges a lens that converts parallel rays of light to converge to a focus and produces a real image. Image formed by a

produced by a lens The image is ALWAYS virtual, right-side up, and smaller than the object.

It makes no difference how far or how near the object is.

A diverging lens is often used used for the viewfinder on a camera The image is virtual when it is right-side up.

Ex: A diverging lens is often used for the viewfinder on a camera *You look through the lens in order to see it. A real image is upside down

Converging Lenses are used for
projecting pictures on a screen. Constructing Images thourgh Ray Diagrams Converging Lens
