Electromagnetic Radiation

Rainbow science anyone? learners put the color specturm, frequency, light waves, and wavelengths into a light speed context. They use algebraic formulas to determine the speed of each light wave length. A great way to connect math and...

Finally, an electromagnetic spectrum lab that will get glowing reviews from your class! Explore the nature of light using red and blue LED sources and fantastic phosphorescent paper. Young scientists compare the effects of blue light...

This short slide show applies the electromagnetic spectrum to astronomy. First, electromagnetic radiation is introduced to viewers. Wavelength is defined and its unit of measurement explained. Finally, aspiring astronomers find that the...

Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

Any work with light, lenses, lasers, or mirrors is called optical engineering. Optical engineers bend and bounce light to make it useful for humans. Examples are telescopes, invisibility, nanomedicine, and solar energy. This...

[Free Registration/Login may be required to access all resource tools.] Students investigate the fundamentals of light including its source, how it is defined for measurements, how we perceive color, and the situations that make an...

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...
