Electromagnetic Waves: Definition, Sources & Properties

1. Electromagnetic Waves: Definition, Sources & Properties

In this lesson, learn the basics of electromagnetic waves and how they make up the electromagnetic spectrum. We will explore the major trends and categories within the spectrum, as well as the various sources of electromagnetic waves.

Technological Applications of Electromagnetic Waves

2. Technological Applications of Electromagnetic Waves

After completing this lesson, you will be able to explain what electromagnetic waves are and provide some applications of each type of electromagnetic wave. To see just how much you have learned, take the short quiz at the end of the lesson!

The 7 Major Regions of the Electromagnetic Spectrum

3. The 7 Major Regions of the Electromagnetic Spectrum

This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.

The Nature of Light: Origin, Spectrum & Color Frequency

4. The Nature of Light: Origin, Spectrum & Color Frequency

This lesson introduces the basics of visible light and color. Learn how the visible light spectrum is divided into the six color ranges. We'll also discuss why different people name colors in different ways.

Color: White Light, Reflection & Absorption

5. Color: White Light, Reflection & Absorption

What gives color to objects? How do light waves interact with materials to produce red and green or white and black? In this lesson, learn how white light is composed of all colors and how absorption and reflection influence our color perception.

The Wave Theory of Light: Definition & Evidence

6. The Wave Theory of Light: Definition & Evidence

After completing this lesson, you will be able to explain what light is and why we thought it was nothing but a wave before the 20th century. At the end, test what you've learned with a short quiz.

Ray Diagrams & Lenses: Physics Lab

7. Ray Diagrams & Lenses: Physics Lab

After completing this lab, you will be able to explain how lenses work, explain the difference between convex and concave lenses, draw ray diagrams to analyze the image produced by a lens, and apply that understanding to eyeglasses.

Telescopes & the Electromagnetic Spectrum

8. Telescopes & the Electromagnetic Spectrum

This lesson will teach you about which forms of light can reach the ground and which cannot and how we overcome this problem. We'll go over the concept of seeing as well as why we send telescopes into space.

What is an Electron Microscope? - Definition, Types & Uses

9. What is an Electron Microscope? - Definition, Types & Uses

Find out how we can observe the arrangement of atoms in a crystal, or the small features on the antenna of a wasp. In this lesson you will understand how electron microscopes work and their applications in science and technology.
