About This Chapter
Who's It For?
Anyone who needs help learning or mastering modern physics material will benefit from the lessons in this chapter. There is no faster or easier way to learn about modern physics. Among those who would benefit are:
- Students who have fallen behind in understanding modern and nuclear physics concepts
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about modern physics
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How It Works:

Students Will Review:
This chapter helps students review the concepts in a modern physics unit of a standard introductory physics course. Topics covered include:
- Photoelectric effect
- Wave characteristics of matter
- Bohr model
- Relationship between mass and energy
- Nuclear binding energy
- Types of radioactive decay
- Half-life and decay graphs
- Applications of nuclear chemistry
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. Fourth Dimension: Definition & Overview
The fourth dimension is a mathematical construct used by scientists to describe certain types of phenomena. Learn more about it, subsequently testing your knowledge with a quiz.
9. Takaaki Kajita: Biography & Nobel Prize
A Japanese physicist, Takaaki Kajita, studied the neutrino and uncovered new information about the tiny particle. Learn how his discovery turned a fundamental concept of physics on its head and earned Kajita a Nobel Prize in Physics in 2015.
10. Arthur B. McDonald: Biography & Nobel Prize
Anyone interested in the field of physics and who is in search of information on famous physicists would appreciate this lesson. In this lesson, we will take a look at the life of one of the co-recipients for the Nobel Prize in Physics—Dr. Arthur McDonald.
