Students will calculate energy, frequency, or wavelength. After calculating, students graph their data and answer analysis questions.

Investigate the wavelength properties of visible light and the scattering effects of the earth's atmosphere on different wavelengths.

This is a rockin' project for guitarists with an interest in the physics behind music. If you have ever wondered why the pitch of the note changes when you fret the string, this project will help you understand by applying basic...

Middle schoolers 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.

After looking at a representative two-point source interference pattern with accompanying order numbers, students investigate the rationale behind the numbering system, and develop some mathematical equations that relate the features of...

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...

See the sun like you have never seen it before! Using a specialized telescope, NASA developed images of the sun created from a wide range of wavelengths of light. Each wavelength is represented by a different color making a beautiful...

Find out how some wavelengths of light are scattered more than others producing blue skies and red sunsets.

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,...

Resource focuses on the relationship between the frequency, wavelength and speed of light. Has a link to an interactive activity relating frequency, wavelength, and energy.

This site from Georgia State University discusses the location of visible light on the electromagnetic spectrum. Includes the wavelength values for various colors of light within the visible light spectrum.

Students are introduced to different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn...

A thorough explanation of the wave equation (Speed = Wavelength * Frequency). A data table and questions to check one's understanding are also part of this lesson.

From a course titled "Structure and Interpretation of Signals and Systems." A discussion of the entire radio spectrum, listing wavelength and frequency values for its various parts. The uses of each region of the radio spectrum is...

Students investigate the underlying causes of two-point source interference pattern. They also discover that the spatial separation between the antinodal and nodal lines in the pattern is related to the wavelength of the waves.

Explains what spectrophotometry is, the types of spectrophotometers, and what they are used for.

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare...

The following videos show sunspots using wavelengths of light that the human eye cannot see. Watch sunspots emerging on the earth's surface, a sunspot moving across the earth's surface, and the rotation of the sun as a sunspot evolves...

Describes quasars as being classified within the category of an active galaxy. A description of the emergence of high-energy. Definitions of key words are provided.gamma-ray quasars as an important component of the gamma-ray sky.

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.

A short biography about the scientist who produced and detected electromagnetic radiation in a wavelength range known as X-rays or Rontgen rays, which earned him the first Nobel Prize in Physics in 1901.

[Free Registration/Login may be required to access all resource tools.] Explains what causes single slit interference of light and how to find the wavelength of a single slit interference pattern using a formula.

In this thorough lesson, nodes and antinodes are explained and compared to crests and troughs. A "Check Your Understanding," set of questions is included at the end of the lesson with answers.

Instructional module focusing on waves and wave motion. Discussion includes wave theories, wave basics, and wave speed. The site also includes an interactive practice quiz and links relating to the topic.
