An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

If you are up for constructing a wooden frame, you can do this demonstration of the interference patterns when light reflects off of layers of soapy film. Both constructive and destructive interference can be seen as evidenced by the...

An incredibly colorful PowerPoint presents all the facts and definitions about waves that you could need for beginning physical scientists. There are several useful links to online animations of wave action. This may have been produced...

Physics masters figure out the wavelength of different waves. Looking at a wave graph, they identify different characteristics. Many more problems get them working with both electromagnetic and sound waves. There are a total of 17...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Let there be light! When your physics learners take this midterm exam, light will be their focus. They will show what they know about electromagnetic waves, interference, refraction, reflection, lenses, prisms, and more! The test is...

Lots of definitions are given here, and your students will find the details and links useful, along with the diagrams and examples.

Create jumbo bubbles and use them to teach about surface tension or interference, perfect for a physical science lesson on light or molecular attraction.

In this optics review worksheet, students complete 50 multiple choice questions on light reflection, diffraction and interference.

Students explore constructive interference and destructive interference. In this light travel activity, students follow procedures to discover how light waves travel and experience interference.

Students experiment with wave behaviors.  For this wave machine lesson, students design a model of waves to understand interference, standing waves, free-end reflection and wave velocity.
