Ch 16: Modern Physics: Help and Review

About This Chapter

The Modern Physics chapter of this Physics 101: Help and Review course is the simplest way to master modern physics. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of modern physics.

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:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Modern Physics chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Modern Physics chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any modern physics question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Test your knowledge with a 30-question chapter practice test
The Wave Nature of Matter

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.

The Bohr Model and Atomic Spectra

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.

Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

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.

Types of Radioactive Decay and Their Effect on the Nucleus

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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

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.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

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.

Energy & Momentum of a Photon: Equation & Calculations

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.

Fourth Dimension: Definition & Overview

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.

Takaaki Kajita: Biography & Nobel Prize

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.

Arthur B. McDonald: Biography & Nobel Prize

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.
