About This Chapter
Georgia Milestones- Physical Science EOC: Waves- Chapter Summary
This chapter will teach you everything you need to know about waves, including the characteristics of various types, as you prepare for the Georgia Milestones- Physical Science EOC test. The lesson topics included in this chapter are:
- Transverse vs. longitudinal waves
- Electromagnetic waves
- Mechanical waves
- Characteristics of waves such as wavelength, amplitude and speed
- Pitch vs. volume
- Refraction and dispersion
- Interference (constructive and destructive)
Our experienced instructors lead you through every video lesson in this chapter. The video lessons are short, engaging and are no longer than ten minutes in length. There are lesson transcripts available to you as well. The lesson transcripts have terms in bold print to emphasize important aspects of the lesson. You have the option to watch video lessons, read lesson transcripts or use both. Having these options can help personalize your preparation for the exam.
1. 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.
2. 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.
3. Mechanical Waves: Production & Propagation
What is a mechanical wave? Learn about the types of mechanical waves, how they are produced, and what affects their propagation, then test yourself by taking a quiz.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
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.
11. 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.
