Introduction to Germanium: Properties and Applications
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...

The Nature of Waves: Interaction of Waves
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,...

PHYSICS - Waves - Wave Behaviour
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,...

Hands On Weather II: More Weather Experiments
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"...

Weather Things: Physics of Optics
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...

Animation of a divergent biconcave lens, showing its effect on parallel rays of light. Light is refracted when it passes from air into the more dense medium of the glass lens, slowing it down and changing the angle of its path

Converging lens focussing rays of light, animation.
This is a biconvex lens. The paths of the rays are changed due to refraction, which occurs as the speed of light in glass is lower than the speed in air. The point at which the rays meet is called the focus, and the distance from the...

Triangular prism splitting a ray of white light into its constituent colours.
This occurs because the light is refracted when it passes from the air to the glass, as the speed of light in glass is lower than that in air. Light with a shorter wavelength, at the blue end of the spectrum, is refracted more than the...
