In Spanish. In this interactive unit learn how to calculate intervals of growth and decay, maximum and minimum value of a function, the intervals of concavity and convexity and the turning points of a function.

This lesson explains what lenses are, the different between a converging and diverging lens, the difference between a double convex and double concave lens, and gives definitions for terms related to lenses.

Ray diagrams are useful tools for determining the location of an image as produced by a concave mirror. All concave and convex mirror ray diagrams can be constructed from knowledge of the behavior of two rays. Learn here about ray diagrams.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn how to draw ray diagrams and to solve problems for concave and convex mirrors.

Ray diagrams are useful tools for determining the location of an image as produced by a concave mirror. Of all the rays which emanate from the top of the object arrow and are incident to the mirror, there are two rays whose behavior at...

Kids learn about lenses and light in the science of physics including concave, convex, converging, diverging, focal point, meniscus, and Plano lenses.

[Free Registration/Login Required] This flipchart reviews the characteristics of light and its properties. Students are given examples of reflection, refraction, and lens types. An assessment component is included.

[Free Registration/Login may be required to access all resource tools.] This study guide focuses on polygons: convex vs concave, interior and exterior angles, and basic terminology for common polygons.

Lenses are precisely shaped pieces of glass that have been developed and used in corrective glasses, telescopes, microscopes, binoculars, and magnifying glasses. They can be convex or concave. Links are provided to a video an a test.

This website has basic definitions for most polygons, regular and irregular.

A discussion from Georgia State University of different types of mirrors and the images which they create. Discusses different instruments which use mirrors to produce images.

Explore the effect of concave and convex mirrors. Combine concave and convex mirrors to design a fun house mirror that will create the distorted pictures of Melissa and Sam.

This site from Georgia State University discusses the means by which mirrors and lenses are combined to produce an optical instrument which accomplishes a specific purpose. Good illustrations.
