Students are introduced to the electromagnetic spectrum through this group research activity. Each group investigates a different wavelength range within the em spectrum and reports back to class. Discussion ideas also included.

This video segment adapted from FRONTLINE introduces the electromagnetic spectrum and explains how the various types of electromagnetic waves are distinguished by the amount of energy each wave carries.

The dualistic nature of light is discussed. The photoelectric effect and the Davisson-Germer experiment are contrasted as empirical evidence supporting each of the two views - particle and wave - of the nature of light. The photoelectric...

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the...

Through an introduction to the design of lighting systems and the electromagnetic spectrum, students learn about the concept of daylighting as well as two types of light bulbs (lamps) often used in energy-efficient lighting design....

A tutorial on the electromagnetic and visible spectra. Discusses dispersion and how perceptions of white and black are related to the visible light spectrum.

This article discusses the properties of electromagnetic radiation and photons.

Several pages with an interesting discussion of the visible light spectrum and atomic absorption and emission line spectrum. Features excellent graphics, thorough and understandable discussion, and many interactive Java applets.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

Kids learn about the science of the light spectrum. Wavelengths and frequencies of the electromagnetic waves including visible light, primary colors, and subtractive colors.

Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet.

This resource provides information on the different wavelengths that make up the electromagnetic spectrum. Also contains information on waves and color.

The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.

Middle schoolers learn the basic properties of light--the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the...

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five...

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...

[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...

Using a student-teacher dialogue format, this page discusses the nature of light as an electromagnetic wave and the electromagnetic spectrum.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in...

NASA site provides information on waves, electromagnetic waves and their wavelengths.

In this interactive lesson about electromagnetic waves students will explore what they can see, what they can't, and what they know about the wave nature of this thing called "light."

How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change....

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...
