Optical physics. Explaining and what Refraction, total internal reflection and dispersion is. Refraction is the bending of the light rays path, when it passes a new medium. When the index of refraction is greater in the new medium and...

Refraction Set: 2. This clip explains the atmospheric refraction that includes mirages, rainbows and sunsets.

A blue sky and fluffy bright clouds are things that are seen around the world. The atmosphere presents a multitude of sights and phenomena using light, air, water droplets, ice crystals, and dust. Many of the phenomena give clues to...

Through live action footage and animated diagrams students will come to understand that refraction is the bending of light rays when they go from one medium to another medium of different density. The program explains why light refracts...

Refraction Set: 1. This clip explains the phenomenon of light refraction.

Using real world demonstrations and colorful graphics, Real World Science: Light teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light,...

Explaining how sunlight is refracted and dispersed by water droplets in the atmosphere, this video describes the formation of rainbows and the seven colors that make up their spectrum. The video also explores other unique locations where...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

This video provides an overview of the element germanium. It describes the physical properties of germanium and its discovery by Clemens Winkler. The video also discusses the various uses of germanium, such as in semiconductors, optical...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...

How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal. Transmission, reflection, refraction, diffraction,...

Air and moisture in different quantities comprise our atmosphere. The sun is the energy source that causes temperature change, wind, clouds, rain, dew, blue skies and rainbows. See how to build an instrument called a "sling psychrometer"...

A blue sky and fluffy bright clouds are things that are seen around the world. The atmosphere presents a multitude of sights and phenomena using light, air, water droplets, ice crystals, and dust. Many of the phenomena give clues to...
