we've talked a lot about convex lenses so I thought I would do a quick video on concave in lenses although there aren't as many different combinations of what a concave lens can do so just remember concave has the word cave in it so I always imagine that it's kind of caving in Words caving in where it's a little bit of an exaggerated drawing I think you get the general idea this is a concave

Geometric Optics Purpose: Students will learn about refraction, lenses, and mirrors. Introduction: Few things are as basic as vision. If you are planning to go into a veterinary or medical field, you might be helping patients with eye problems. If not, maybe you just want to know a little more about your own eyeglasses or contact lenses.

Geometrical optics is the treatment of the passage of light through lenses, prisms, etc. by representing the light as rays. A light ray from a source goes in a straight line through the air, but when it encounters a lens, prism, or mirror it bends or changes direction. Lens Prism Mirror Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances.

The basic concepts explored in this discussion, which are derived from the science of Geometrical Optics, will lead to an understanding of the magnification process, the properties of real and virtual images, and Lenses and Geometrical Optics. The action of a simple lens, similar to many of those used in the microscope, is governed by the principles of refraction and reflection and can be understood with the aid of a few simple rules about the geometry involved in tracing light rays through the lens. The basic concepts explored in this discussion, which are derived from the science of Geometrical Optics, will lead to an understanding of the magnification process, the properties of real and virtual Topics Refraction; Lens; Optics; Description How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.
