In this gamma-ray worksheet, students read about the Fermi Gamma-ray Observatory and how it measures the invisible lumps in space. Students solve 3 problems using an equation to determine the time that gamma-rays travel in space and the...

In this measuring star temperatures, students find the temperature of a star using Planck's curve and the Wein Displacement law. Students also find the peak wavelengths for given stars using Planck's curve.

In this space science worksheet, students identify ultraviolet beams and what occurs when the frequency is doubled. They identify how long it would take to send a radio message from a space probe of Mars to earth. Students also determine...

Students examine the concept of frequency and wavelength. They analyze how frequency and wavelength relate to each other by conducting an experiment involving measuring and timing wavelengths by pulling adding machine tape through an...

Students investigate the components of white light as viewed through a prism. The multiple colors of the spectrum produced are related to wavelengths and experienced through the creation of a color wheel.

Sixth graders observe light being separated into a color spectrum.  In this electromagnetic lesson students use a diffraction grating to separate light and compare light sources. 

In this electromagnetic spectrum activity, students review all regions of the spectrum in order from longest to shortest wavelength. Students list all possible values for specific quantum numbers. This activity has 20 problems to solve.

In this light waves learning exercise, students will measure the wavelength of different light waves and then calculate its frequency. This learning exercise has 9 short answer questions and 10 fill in the blank questions.

In this physics worksheet, students observe white light through a spectroscope and describe what they see. Then they observe fluorescent light with the spectroscope and describe what they see. Students also describe why it is important...

In this atoms worksheet, students determine the velocity, wavelength, power, and frequency of given atoms. Student describe wave-particle duality and give the principle and angular quantum numbers for given orbitals. This worksheet has...

Students perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...

Students demonstrate sound waves and make changes in the waves resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.

Student describes what happens to the color of a stove burner or a coal as it gets hotter. They use the applet to determine what range of temperatures range give you a red light, what range of temperatures would give you a white light,...

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,...

This hypertext physics course page illustrates and explains the Doppler effect. Users perform practice calculations for frequency shifts using the Doppler equation.

This analogy story explains the manner in which the wavelength of light affects the maximum resolution of a microscope.

This page defines electromagnetic radiation. Included are links to more information.
