Waves: Components, Types & Parameters

1. Waves: Components, Types & Parameters

After completing this lesson, you will be able to explain what a wave is, describe the various types of waves and measure their features, like components and parameters. A short quiz will follow.

Sound: Definition, Influences, Pitch & Volume

2. Sound: Definition, Influences, Pitch & Volume

What is a sound? Learn about sounds and what influences how we perceive them, including pitch and volume. Test your understanding of sound features and finish off with a quiz.

Electromagnetic Waves: Definition, Sources, Properties & Regions

3. Electromagnetic Waves: Definition, Sources, Properties & Regions

Electromagnetic waves power everything from your computer's Internet connection to your radio to atomic weapons. In this lesson, we'll look at the entire spectrum, as well as how they are formed and characteristics of each group of waves.

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.

Reflection: Angle of Incidence, Curved Surfaces & Diffusion

5. Reflection: Angle of Incidence, Curved Surfaces & Diffusion

How does light bounce off surfaces? Learn the differences between how light bounces off flat surfaces, curved surfaces, and non-shiny surfaces. Then reflect on your reflection knowledge with a quiz.

Resonance: Definition & Transmission of Waves

6. Resonance: Definition & Transmission of Waves

This lesson describes how sound and light waves are affected by the principle of resonance. Learn how resonance occurs through the vibrations and resonant frequencies of objects. You'll investigate everyday examples of resonance and learn how to break a wine glass with your voice!

Transparent and Opaque Materials in Electromagnetic Waves

7. Transparent and Opaque Materials in Electromagnetic Waves

What makes an object transparent or opaque? How does light pass through some objects and not others? And what about the other types of electromagnetic waves? We'll investigate all these questions in this lesson about the transparency and opacity of materials.

Color: White Light, Reflection & Absorption

8. 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.

Refraction, Dispersion & Diffraction

9. Refraction, Dispersion & Diffraction

Learn about light waves and how they can be affected by objects. Explore the difference between refraction, dispersion, and diffraction. Take the quiz to see how much you can remember.

Constructive and Destructive Interference

10. Constructive and Destructive Interference

What happens when one wave meets another? Do the waves converge to make one giant wave? Or, do they destroy each other? In this lesson, we'll explore the workings of wave interference.

The Doppler Effect: Definition, Examples & Applications

11. The Doppler Effect: Definition, Examples & Applications

What is the Doppler effect? How does it affect our perceptions of sound and light? In this lesson, learn how traveling wave sources can change the way we observe sound and light waves. Explore the applications of the Doppler effect on shock waves, sonic booms, and the movements of distant galaxies.
