Ch 22: Modern and Nuclear Physics

About This Chapter

In this chapter, you will find brief, engaging video lessons to help learn or review the essential concepts of modern and nuclear physics. Take the short, multiple-choice quizzes and chapter exam to help gauge your understanding of these concepts.

Modern and Nuclear Physics - Chapter Summary

Whether you need help learning physics, reviewing what you've already learned or preparing for an important exam, this chapter will guide you through all the essential topics of modern and nuclear physics. Can you explain what is meant by wave-particle duality or use the de-Broglie wavelength equation? How are quantum numbers related to the creation of light? What is so important about the nucleus of a helium atom? In this chapter you will learn the answers to these questions as you review lessons about:

  • The Photoelectric Effect
  • The Bohr Model
  • Mass-Energy conversion
  • Using half-life to calculate radioactive decay
  • Nuclear fusion and fission
  • Carbon dating

Subject matter experts have created video lessons that are short, succinct, thorough and engaging. These instructors are also only a click away to answer any questions that arise as you proceed through the chapter. The videos can be watched as many times as you need and each video has tags to easily jump back and forth to content within. Following each lesson there is a short, multiple-choice quiz so you can assess your comprehension. Take the exam at the end of the chapter to ensure you retained everything you were hoping to learn about modern and nuclear physics.

The Photoelectric Effect: Definition, History, Application & Equation

1. 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.

Energy & Momentum of a Photon: Equation & Calculations

2. Energy & Momentum of a Photon: Equation & Calculations

After watching this lesson, you will be able to explain what wave-particle duality is, provide the equations for the energy and momentum of a photon of light, and use those equations to solve problems. A short quiz will follow.

The Wave Nature of Matter

3. The Wave Nature of Matter

After watching this video, you will be able to explain the concept of wave-particle duality, give an example of an application of wave-particle duality, and complete simple calculations using the de-Broglie wavelength equation. A short quiz will follow.

The Bohr Model and Atomic Spectra

4. The Bohr Model and Atomic Spectra

Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.

Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

5. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

When you hear the term 'nuclear power,' what comes to mind? Do you know where that energy and power is coming from? In this lesson, we are going to zoom in on the nucleus of a helium atom to explain how something as small as a nucleus can produce an extremely large amount of energy.

Types of Radioactive Decay and Their Effect on the Nucleus

6. 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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

7. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.

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.
