Ch 62: Modern Physics Principles

About This Chapter

Improve your understanding of modern physics principles with this overview that includes radioactive decay, atomic nucleus, and more. These short lessons are a helpful tool for students preparing for an exam or catching up on missed class time.

Modern Physics Principles - Chapter Summary

The lessons in this chapter provide an overview of modern physics principles. You will review different types of nuclear decay particles and gain a better understanding of nuclear physics. After completing the chapter, you should be prepared to:

  • Describe the structure of the atomic nucleus
  • Discuss the history of the photoelectric effect
  • Explain Moseley's law
  • Differentiate between characteristic and continuous x-rays
  • Recall how fusion and fission work
  • List three types of radioactive decay
  • Discuss applications of nuclear chemistry

Each lesson comes with a brief quiz to ascertain how much of the content you can recall. Video timelines let you navigate the lessons and study only the topics you need to review. Make the most of the chapter by studying offline when you print the quiz in worksheet form.

Atomic Nucleus: Definition, Structure & Size

1. Atomic Nucleus: Definition, Structure & Size

The atomic nucleus is the central part of the atom. There is a lot to be told by the structure of the atomic nucleus. This lesson goes through the structure of the atomic nucleus and other factors that the atomic nucleus tells us.

The Photoelectric Effect: Definition, History, Application & Equation

2. The Photoelectric Effect: Definition, History, Application & Equation

In this lesson, you will learn what the photoelectric effect is, how it was discovered, how it applies to everyday life, and the equation associated with it. A short quiz will follow.

Henry Moseley: Biography & Atomic Theory

3. Henry Moseley: Biography & Atomic Theory

Physicist Henry Moseley discovered the atomic number of each element using x-rays, which led to more accurate organization of the periodic table. We will cover his life and discovery of the relationship between atomic number and x-ray frequency, known as Moseley's Law.

Characteristic vs. Continuous X-Rays: Properties & Comparison

4. Characteristic vs. Continuous X-Rays: Properties & Comparison

In this lesson, you'll learn the difference between characteristic X-rays and continuous X-rays. We'll explore properties of each and take a look at how characteristic X-rays and continuous X-rays are produced.

Nuclear Physics: Nuclear Force & Building Energy

5. Nuclear Physics: Nuclear Force & Building Energy

After watching this video, you should be able to explain what nuclear physics is, including the concept of binding energy. You should also be able to explain how fusion and fission work. A short quiz will follow.

Radioactive Decay: Definition, Formula & Types

6. Radioactive Decay: Definition, Formula & Types

In this lesson, we'll discuss radioactive decay and learn the terms parent nucleus, daughter nucleus, and half-life. We'll also examine three types of radioactive decay.

Types of Radioactive Decay and Their Effect on the Nucleus

7. Types of Radioactive Decay and Their Effect on the Nucleus

What is meant by the term 'radioactive'? In this lesson we will break down the three main types of nuclear decay particles and discuss their composition, their effect on the nucleus, and their applications.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

8. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
