Ch 38: Chapter 38: The Atom and the Quantum

About This Chapter

The Atom and the Quantum chapter of this Prentice Hall Conceptual Physics Companion Course helps students learn the essential lessons associated with the atom and quantum physics. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Atom and the Quantum textbook chapter.

How It Works:

  • Identify the lessons in the Prentice Hall Atom and the Quantum chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the atom and quantum physics topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • What the photoelectric effect is
  • The concept of wave-particle duality
  • Neils Bohr's scientific contributions
  • How to calculate the de-Broglie wavelength
  • Atomic and ionic radii trends in the periodic table
  • Key theories in quantum physics

Energy & Momentum of a Photon: Equation & Calculations

1. 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 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.

Wave-Particle Duality: Concept, Explanation & Examples

3. Wave-Particle Duality: Concept, Explanation & Examples

Is light a particle with mass and substance? Or, is it just a wave traveling through space? Most scientists say light is both a particle and a wave! Find out how they came to this strange conclusion as we learn about the theory of wave-particle duality.

Neils Bohr: Discovery & Biography

4. Neils Bohr: Discovery & Biography

Read about one of the most important contributors to modern physics, Niels Bohr. The Danish scientist led a fascinating life devoted to science, but also to peace after escaping Nazi-occupied Europe in the 1940s.

The Wave Nature of Matter

5. 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.

Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

6. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.

Quantum Physics: Definition, Theories & Topics

7. Quantum Physics: Definition, Theories & Topics

While exploring this lesson, you will learn what quantum physics, otherwise known as quantum mechanics, is, examine some of its theories and topics, and discover the weird consequences that go along with it. A short quiz will follow.
