Atoms and Light The movement of electrons inside of atoms produces light and other electromagnetic radiation. Sunlight produces every color in the rainbow but… Each element gives off only certain frequencies of
Lesson 2-1 X-rays and radio waves are some of the other types of electromagnetic waves. Scientists classify electromagnetic waves into groups based on their wavelengths and frequencies. What is light? (cont.) Lesson 2-1 What is light? (cont.) How are waves in the electromagnetic spectrum di...
Here is a multi-segment excerpt of Applied Electro Optics, by Louis Desmarais. Sometimes, it's just necessary to go back to the basics and this chapter, Light and the Electromagnetic Spectrum, does just that. This segment covers wave motion.Louis Desmarais...
Light refers to a small part of the electromagnetic spectrum that our eyes can seeSunlight consists of light with a continuous range of wavelengths and frequencies When sunlight passes through a prism, the light separates into a spectrum of colors Light and Atomic SpectraEach color in the ...
