Electromagnetic Spectrum

Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

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...

The University of Hawaii has published a vast collection of midterm and final exams for their Physics 152 course. This particular exam offers a variety of assessment methods, and covers the topic of electromagnetic radiation....

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...

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,...

Investigate color, light and excited electrons and produce waves using slinkys. Your high schoolers will observe a continuous spectrum with a prism and an overhead projector. They observe flame tests to identify elements and they observe...

What can the electromagnetic spectrum tell us about the sun? As it turns out, quite a bit! See the sun in a whole new light with a video from NOVA's Sun Lab unit. The narrator describes the electromagnetic spectrum in terms of visible...

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...

Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...

Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.
