Ch 13: TExES Science 7-12: Optics & Waves

About This Chapter

Familiarize yourself with optics and waves so you're ready for related questions on the TExES Science 7-12 exam. This chapter's lessons help you go over information about several types of waves.

TExES Science 7-12: Optics & Waves - Chapter Summary

Use this chapter to refresh your understanding of optics and waves to for the TExES Science 7-12 test. The lessons cover the components and parameters of waves as well as the applications of physics in medicine. By using these lessons, you should be able to:

  • Define the influences, pitch and volume of sound
  • Describe the nature, origin, spectrum and color frequency of light
  • Explain refraction, angles of incidence, curved surfaces and diffusion
  • Understand resonance and the transmission of waves
  • Identify transparent and opaque materials in electromagnetic waves
  • Summarize refraction, dispersion and diffraction
  • Share applications of the Doppler effect
  • Compare transverse and longitudinal waves

Our lessons break down information about each type of wave and present this subject matter in a clear, engaging way. The quizzes that accompany each lesson give you a chance to practice putting what you know into practice.

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.

Transverse & Longitudinal Waves: Definition & Examples

3. Transverse & Longitudinal Waves: Definition & Examples

What comes to mind when you think of a wave? Chances are your mental image takes the form of a transverse wave. But, longitudinal waves are just as important, and understanding the difference is vital to learning about waves. In this lesson, explore both types of waves and the unique characteristics of each.

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.

Refraction, Dispersion & Diffraction

8. 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.

The Application of Physics in Medicine

9. The Application of Physics in Medicine

After completing this lesson, you will be able to explain how and why physics is used in the medical profession, as well as provide some examples. A short quiz will follow the lesson summary.

The Doppler Effect: Definition, Examples & Applications

10. 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.
