About This Chapter
OAE Integrated Science: Waves, Light & Sound - Chapter Summary
This chapter focuses on the relationships between waves, light, and sound. It will help you recall the characteristics of waves, such as amplitude, periods, frequencies, and speeds. It will then examine the formal definition of sound as well as the special characteristics of sound. The last category, light, features the most lessons. The lessons on light will cover the nature of light, reflection, diffraction, and more. By the end of the chapter you will have reviewed:
- Energy, motion, vibration, and waves
- The definition of wave parameters
- Examples of longitudinal and transverse waves
- The definition of sound
- Pitch, volume and electromagnetic waves
- The electromagnetic spectrum
- Opaque materials
- Color, refraction, dispersion, reflection, the nature of light
- The Doppler effect
- The meanings of destructive and constructive interference
- Wave-particle duality
We have created a series of quizzes that are very similar to the ones on the OAE Integrated Science exam. The study guide offers these quizzes at the end of each lesson. Completing these practice exams will help you sharpen your test-taking strategies.
Objectives of the OAE Integrated Science: Waves, Light & Sound Chapter
The computer-based OAE Integrated Science exam assesses your knowledge of four domains: Earth science, life science, physical science, and the nature of science. This chapter connects to the physical science domain. This domain is the most important; approximately 37% of the 150 multiple-choice questions will be about physical science. It is important to have some sort of prior experience with these types of questions, as well. The test is only 180 minutes long, so preparing yourself with our study guide and practice tests will help you learn to budget your time.
1. Vibrations and Waves: Energy and Motion
What is a wave? What causes waves, and how do they travel from one place to another? This lesson will guide you through the basics of waves. We'll discuss their origins from vibrations and investigate how they carry energy through a medium.
2. Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed
How do we measure and describe waves? How do waves differ based upon their shapes? This lesson will guide you through the five wave parameters - period, frequency, amplitude, wavelength, and speed - that we use to characterize waves.
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.
4. What is Sound? - Definition and Factors Affecting the Speed of Sound
Explore the minute workings of sound waves and how they travel. We'll discuss the main factors that affect the speed of sound waves, and we'll try some mathematical problems involving the wave equation.
5. Pitch and Volume in Sound Waves
What do pitch and volume mean when talking about sound waves? Further your understanding of sound waves in this lesson as we explore the more familiar aspects of sound. We'll learn about pitch and volume and how they relate to sound wave parameters.
6. 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.
7. 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.
8. 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.
9. Reflection: Angle of Incidence and Curved Surfaces
How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.
10. Diffuse Reflection: Definition, Examples & Surfaces
This lesson explores the law of reflection and how it applies to different surfaces and wave types. We'll learn the difference between specular and diffuse reflection and investigate how diffuse reflection affects our perception of sound and light.
11. 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.
12. 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.
13. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction
Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.
14. Diffraction: Relation to Sound & Light and Effects of Wavelength
This lesson explores diffraction as one of the many behaviors of waves. Learn how diffraction occurs in sound and light waves and how it is affected by the wavelength of a wave. Find out how animals use diffraction to communicate and how scientists use it to study molecules.
15. 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.
16. 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.
17. Wave-Particle Duality: Concept, Explanation & Examples
Is light a particle with mass and substance? Or, is it just a wave traveling through space? Most scientists say light is both a particle and a wave! Find out how they came to this strange conclusion as we learn about the theory of wave-particle duality.
