About This Chapter

The Sound chapter of this MCAT Prep Help and Review course is the simplest way to master sound wave behavior. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of sound for the MCAT.

Who's it for?

Anyone who needs help learning or mastering MCAT material will benefit from taking this course. There is no faster or easier way to prepare for the MCAT. Among those who would benefit are:

  • Students who have fallen behind in understanding factors that affect the amplitude, frequency and speed of sound waves
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about sound for the MCAT
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.

What is Sound? - Definition and Factors Affecting the Speed of Sound

1. 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.

The Doppler Effect: Definition, Examples & Applications

2. 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.

Pitch and Volume in Sound Waves

3. 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.

Sound Attenuation: Definition & Effects

4. Sound Attenuation: Definition & Effects

What exactly is sound, how does it travel, and why does it change volume? There are a lot of questions we can ask about sound, and in this lesson, we'll explore the idea of sound attenuation to explain a few of them.

What Is Ultrasonography? - Definition, History & Uses

5. What Is Ultrasonography? - Definition, History & Uses

Ultrasonography is a diagnostic medical procedure that uses sound waves to produce images on a screen, which allows medical providers to view internal structures of the body. In this lesson, you'll learn more about ultrasonography and its uses.
