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.
A wave carries energy from one point to another through a medium. Types of waves include light, sound, electromagnetic, mechanical, transverse, and longitudinal. Explores a wave's characteristics, such as amplitude, frequency, and wavelength. Also presents the four ways waves interact with mediums. Defines terminology as it is introduced. Quiz after summary.
Is light composed of waves or particles? Explores the wave model of light from its earliest roots to our modern understanding of electromagnetism in 17 computer-animated video modules. Expresses Empedocles' belief that light streams from the eye, Aristotle's conception of light as a disturbance in ether, and Euclid's mathematical, ray-centered paradigms. Presents the Cartesian sine wave model, Huygens' principle of bending wave fronts, the electromagnetic spectrum, and aspects of particle theory. Provides an overview of diffraction, interference, polarization, and dispersion. Also explains Young's double-slit experiment.
Students investigate the features of vibrations and waves. Examples of these phenomena help students understand how sounds are formed, how light travels, and how ocean waves move. Students also explore different types of waves such as microwaves, radio waves, and seismic waves. Concepts and terminology include vibration, energy, wave, light, and sound.
There’s a new renewable energy player in town, and it’s about to make waves in the industry. Despite its massive potential as a source for renewable energy, the ocean is unlikely to contribute meaningfully to electricity supplies without dramatic, innovation-driven reductions in the cost of energy conversion. That’s where engineers Balky Nair, Rahul Shendure, and Tim Mundon come in with their company, Oscilla Power. With support from the National Science Foundation, they’re developing a utility-scale wave energy harvester called the Triton. This technology shows promise as a means for delivering utility-scale electric power to the grid at a price that is competitive with conventional fossil or renewable technologies.

Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story;" approach to explaining these natural phenomena. In this episode, it is night time and Moko can't sleep. Looking out to the horizon, he notices a shot of color at the water's surface. He wakes Mei-Lei to ask her what he is seeing. Together they take a barge and set off. Under them, a rainbow of colors is dancing in the waves. Moko and Mei-Lei think that the fish must be organizing a party and decide to dive in. Bit by bit the sun is rising and day is breaking. The two friends return to the village, overjoyed at the wonders of the ocean.
Imagine having the ability to manipulate light waves in order to see through a skull right into the brain, or being able to use lasers to diagnose a bacterial infection in a matter of minutes. At the Center for Biophotonic Sensors and Systems (CBSS) at Boston University, technologies enabling these abilities and many others are coming to light. With support from the National Science Foundation (NSF), mechanical engineer Thomas Bifano and his colleagues are developing optical microscopes that can image deep into biological tissue, helping scientists observe molecular-scale activity. Their goal is to revolutionize the diagnosis and treatment of disease. Part of the National Science Foundation Series “Science Nation.”
Visible light, which can be seen with human eyes, comprises a small sliver of the electromagnetic spectrum. The rest of the spectrum, from short wavelength gamma rays to long-wavelength radio waves, requires special instruments to detect. ALMA uses an array of radio telescopes to detect and study radio waves from space. ALMA is an advanced tool for studying very old stars and galaxies. These objects now are seen at great cosmic distances, with most of their light stretched out to millimeter and sub-millimeter wavelengths by the expansion of the universe. ALMA provides the unprecedented ability to study the processes of star and planet formation.
How did 20th-century physics change long-held notions of light's makeup and behavior? This group of 12 concise computer-animated videos illustrates Einstein's monumental contributions to the study of light. Shows how rudimentary ideas of material wave motion yielded to more advanced concepts of electromagnetic waves by detailing Einstein's conclusions about the speed of light and his conception of time, which-given his findings on mass and energy-proceeds according to variable frames of reference. Conveys relativistic thought experiments through helpful animation, which demonstrate simultaneity, time dilation, length contraction, and relativistic mass.
From a table at a bar, on a corner of the city of Buenos Aires, we discovered the nature of some of the “wave motion phenomenon” that surrounds us. Some of these were radio and TV waves or the ones from the microwave in the kitchen, solar light, X-rays and cosmic waves.
An elementary class prepares for a visit from the Shadow Players, a group who use light, shadow, and color to tell a story. The class learns about sources of light, shadows, and silhouettes. They experiment with transparent, opaque, and translucent objects to see what lets light through. Using a prism, they discover the colors in light. Review at the end.
When an earthquake hits, it sends seismic waves through the ground. Find out about seismic waves in this animation.
Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

What is light? What are some of the ways people use light? In this program, students develop a basic understanding of light and its uses. The fundamental characteristics of light are highlighted. Concepts and terminology discussed include: night, day, solar energy, and reflect.
Longitudinal waves carry energy through air, water, and solids. They compress and expand the medium in the same direction as the energy is transferred.
Waves are all around. They are a disturbance that travels through space and matter transferring energy from one place to another. Find out about the nature, shapes, and impacts of waves in this animation.
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.
Olli cannot understand why a light is turned off when it is not needed, since it is so easy to flick the switch. Thanks to Suzie, the children get to meet "Power," who can indeed create ample electricity. They also learn a lesson about conservation and natural resources. Part of the "My Little Planet" series.
