Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

Ninth graders are introduced to the components of compressional and transverse. They practice answering speed problems involving different mediums that waves travel trhough and then review the wave PowerPoint. They then visit physics...

Students study the basic structure of the atom. In this chemistry lesson, students explain how colors relate to energy that electrons emit. They calculate energy of the emitted photons.
