Modern Physics and Nuclear Physics - Chapter Summary and Learning Objectives

Watch video lessons in this chapter and learn about the photoelectric effect and photons. You'll study the wave nature of matter and learn how the Bohr model is related to atomic spectra. The instructors who lead these lessons teach you about the relationship between mass and energy and explore different types of radioactive decay and how they affect the nucleus. At the end of this chapter, you'll be familiar with:

  • Applications for linear momentum conservation
  • Mass-energy conversion
  • Radioactive decay calculations
  • Fusion and Fission
  • Carbon dating

Video Objectives
Photons and the Photoelectric Effect Relate the energy of a photon in joules to its wavelength and the linear momentum of a photon to its energy or wavelength.
The Wave Nature of Matter Explain how matter exhibits wave characteristics described by the De Broglie wavelength.
The Bohr Model and Atomic Spectra Draw the Bohr model of the hydrogen atom and explain how it relates to atomic spectra.
Mass and Energy: Description and Interchangeable Relationship Discuss the theory of relativity and how it states that mass and energy are interchangeable.
Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy Explain the relationship between mass and energy. Define mass defect and nuclear binding energy.
Types of Radioactive Decay and Their Effect on the Nucleus List the different types of radioactive decay and describe their shielding requirements and effects on the nucleus.
Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs Perform calculations involving half-lives and use a graph to determine the half-life of a radioactive sample.
Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry List and explain applications of radioactive nuclides.

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.
