What does a mirror tell us about light? Illustrates 11 computer-animated video units for one aspect of light's behavior-reflection. Euclid's geometric optics and his findings on the perception of distance and perspective lead to a discussion of the Law of Reflection, linking angle of incidence with angle of reflection, and the concepts of absorption, transmission, and diffuse reflection. Explains the principles involved with plane, concave, and convex mirrors, including vertex, principle axis, center of curvature, radius of curvature, and virtual image. Shows a group of "mirror equations" how an object's location can be determined by using the laws of reflection.

In this episode, host Dianna Cowern asks the question, “What happens to an image when bending a spoon from concave to convex?” Part of the “Physics Girl” series.
What is light? How does it operate? What are its properties? Why is it so important to the foundations of our physical world? Examines the nature of light and how it's harnessed in our lives. Explains the basic properties of light and the wave model. Also, discusses the concepts of wavelength, frequency, speed, reflection, refraction, total internal reflection, and dispersion. Explains the EMR spectrum, the color of objects, and the addition and subtraction of colors.
Everyday examples and laboratory experiments explain and demonstrate the concept of waves as they relate to physics. Three segments cover the characteristics of transverse and longitudinal waves and the reflection and refraction of waves. Complex physics is made clearer by the lab demonstrations.
Students will learn how light is measured. Visual diagrams and hands-on experiments help students understand how light works. Important terminology includes wave, electromagnetic spectrum, wavelength, energy, reflection, lens, and prism.
Using real-world demonstrations and colorful graphics, students explore how light travels and how different mediums can affect light, resulting in reflection, refraction, and absorption. The color spectrum is also discussed through the use of prisms and paints. Part of the "Real World Science" series.
