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.

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...

This lesson introduces the concepts of wavelength and amplitude in transverse waves. In the associated activity, students will use ropes and their bodies to investigate different wavelengths and amplitudes.

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...

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.

Music and sound are two different concepts that share much in common. Determining the difference between the two can sometimes be difficult due to the subjective nature of deciding what is or is not music. The goal of this activity is to...
