It is cowabunga time! Pupils read an article about the NASA LISA mission on gravitational waves and conduct additional research on them. The class participates in a science bowl type competition about gravitational waves. Panels of four...

Hear from deep space. Pupils learn how satellites transfer information back to Earth. They learn about three different ways to modulate radio waves and how a satellite sends information with only 0s and 1s. Using sound, class members...

Take a look with another perspective. Pupils read to find out what portion of the electromagnetic spectrum a space telescope sees and the difficulties of viewing infrared radiation from other objects in space. Individuals discover how...

To understand how bounded waves behave and how reflection of waves affects the wave components.

With this article, students can learn about and understand the concept of wave motion.

A very simple device to convert light into sound can be made by wiring a solar cell directly to headphones (or an earpiece). The solar cell converts light into electricity and the headphones convert electricity into sound. The limitation...

Learn about the diffraction of light using the wave model and Huygen's principle.

An article that discusses the coupling of an electric field with a magnetic field to create electromagnetic waves. Article also discusses how different types of electromagnetic waves have different wavelengths which forms the...

This article helps illustrate the behavior of electrons as waves and the uncertainty principle.

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity to light an LED. No battery or complex circuitry is required. The device can form the basis of a range of...

Do you know why the sky is blue? Article defines scattering and how it works. Explains the difference between the scattering of light and reflection or refraction.

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...

Students learn about the properties of light as a photon and the wave-particle duality.

Review the key terms and skills related to wave interference, including how to predict wave interference patterns.

This article discusses the properties of electromagnetic radiation and photons.

This essay from the NOVA Web site explores the impact Einstein made on physics and most everything we know about the cosmos.

The interference of two sets of circular waves with the same frequency and the same amplitude results in a standing wave pattern. These standing wave patterns are known as two-point source interference patterns since they result from the...

Article goes into detail about what exactly is interference.
