Ch 24: Modern & Nuclear Physics

About This Chapter

Watch video lessons to explore key concepts in modern and nuclear physics. Review radioactive decay, mass-energy conversion, the photoelectric effect and the uses of nuclear chemistry.

Modern & Nuclear Physics - Chapter Summary

This chapter's video lessons will review important concepts and terms from modern and nuclear physics. Our instructors guide you through the discovery of the photoelectric effect and its applications. You'll also study radioactive decay, nuclear chemistry, atomic spectra and the relationship between mass and energy. Once you watch all of the video lessons, you should be able to:

  • Define the photoelectric effect
  • Discuss the energy and momentum of photons
  • Understand the concept of wave-particle duality
  • Describe the Bohr model of the atom
  • Explain the relationship between mass and energy
  • Define nuclear binding energy and mass defect
  • Identify the types of radioactive decay
  • Calculate radioactive decay using the half-life
  • Give examples of nuclear chemistry applications

To make your review of modern and nuclear physics a simplified process, we offer multiple tools. Our video lessons contain many graphics and examples to help you understand major concepts. The videos also contain tags, which allow you to rewatch excerpts without having to go through entire lessons over again. We provide transcripts of each video as another study tool. Once you feel prepared, take the self-assessment lesson quizzes to find out how well you've grasped the chapter material.

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.

Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

4. 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

5. 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

6. 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

7. 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.

Electron Cloud: Definition, Model & Theory

8. Electron Cloud: Definition, Model & Theory

Like the rapidly moving blades of a fan, electrons appear to occupy all of the space in an atom at once. Learn how electron location in an atom is best described by the electron cloud model and theory.

Nuclear Magnetic Resonance Spectroscopy: C-13 vs 1H

9. Nuclear Magnetic Resonance Spectroscopy: C-13 vs 1H

The primary purpose of this lesson will be to get a foundational understanding of C-13 and H-1 NMR and how they can provide valuable structural information about organic compounds.

What is a Quark? - Definition, Structure & Uses

10. What is a Quark? - Definition, Structure & Uses

Quarks are fundamental particles that are used by scientists to explain different types of phenomena. Learn more about them, subsequently testing your knowledge with a quiz.

Standard Model of Particle Physics

11. Standard Model of Particle Physics

After completing this lesson, you will be able to explain what the standard model of physics is, name the particles that are part of the standard model, and some of the things it can't currently explain. A short quiz will follow.
