Describes the characteristics of light, presents two formulas for calculating its wavelength, and provides a table of the different wavelength ranges across the electromagnetic spectrum.

You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other...

In this interactive activity adapted from the University of Utah's ASPIRE Lab, students will learn how to measure wavelengths and see how wavelength affects the color of the light that we see.

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also...

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

Read about the visible light spectrum and learn the frequencies and wavelengths for each of the primary and secondary colors.

[Free Registration/Login may be required to access all resource tools.] Explains the terms diffraction, interference, and interference patterns. Describes the double slit experiment and how to determine the wavelength of a double slit...

In this very detailed lesson plan from NASA, students investigate wavelength and frequency within the electromagnetic spectrum.

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

Find out whatever you wanted to know about rainbows and how they form. Check out the section on folklore regarding rainbows too.

This Imagine the Universe site provides an introduction into the multiwavelength universe and astronomy. Site provides graphics, links to a quiz, facts on this topic as well as teacher resources.
