The Bohr Model and Atomic Spectra

1. 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.

Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

2. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

Each electron inside of an atom has its own 'address' that consists of four quantum numbers that communicate a great deal of information about that electron. In this lesson, we will be defining each quantum number and explaining how to write a set of quantum numbers for a specific electron.

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.

The Photoelectric Effect: Definition, History, Application & Equation

4. 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.

Blackbody & Blackbody Radiation Theory

5. Blackbody & Blackbody Radiation Theory

This lesson will go over the perfect absorber and emitter of radiation, something called a blackbody, as well as the concept of blackbody radiation and electromagnetic radiation.

What Are Radioactive Substances? - Examples & Uses

6. What Are Radioactive Substances? - Examples & Uses

This lesson will explain what a radioactive substance is, give examples of radioactive substances and describe how radioactivity is used in everyday life.

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.

Radiometric Dating: Methods, Uses & the Significance of Half-Life

8. Radiometric Dating: Methods, Uses & the Significance of Half-Life

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.

Nuclear Reaction: Definition & Examples

9. Nuclear Reaction: Definition & Examples

Learn the differences between a nuclear reaction and a chemical reaction. Also learn how the nuclear reaction involves subatomic particles including protons and neutrons. Discover the different types of nuclear reactions including fission and fusion and also how a nuclear power plant works to produce energy.

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

10. 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.

Theory of Relativity: Definition & Example

11. Theory of Relativity: Definition & Example

Watch this video lesson, and you will learn about the theory of special relativity and how it applies to you. Learn how you can use one of the most famous equations from this theory to calculate the power inside just one tiny object.
