Focusing Light With a Lens

Young scientists know it is hotter along the equator, but why is it also rainier? Through the process of completing two experiments and a worksheet, scholars discover the answer is the intertropical convergence zone. First, they...

Does light always travel in a straight line? The narrator of a short video discusses the path light travels when going between different mediums and points out that light will want to travel on the path that minimizes the travel time....

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Data can tell us a lot about celestial objects that are just too far away to study otherwise. Learners examine data on the brightness of an asteroid to predict its rotation rate. Graphing the data reveals a periodic pattern that allows...

This is an informative site from Georgia State University. It gives a discussion of the thin lens equation and an illustration of its use in determining the image distance based upon the object distance and the focal length.

Explore the connection of light, reflection, and mirrors. A comprehensive lesson introduces the basics of light in relation to reflection and mirrors. After an explanation of the vocabulary, the presentation shows how to create ray...

Magnifying glasses and cameras often use converging lenses, but how do they alter an image? Pupils discover a lens, axis, and object arrow before identifying four characteristics of the resulting image. They label the location,...

This lab is designed to have students investigate the changes that occur to images formed by converging lenses based on the focal length of the lens, the height of the object and the location of the object. This video will help...

The purpose of this tutorial is to summarize object-image relationships by dividing the possible object locations into five general areas or points.

This video offers examples of using the thin lens equation.[12:56]
