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.
3. Planck's Constant: Formula & Application
After watching this lesson, you will be able to explain what Planck's constant is and use the Planck-Einstein relation to calculate the energy in a photon of light. A short quiz will follow.
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.
5. Wave-Particle Duality & the Davisson-Germer Experiment
After watching this video, you should be able to explain what wave-particle duality is, explain how the Davisson-Germer experiment contributed to our evidence for it, and use the de Broglie equation to solve problems. A short quiz will follow.
6. Nuclear Physics: Nuclear Force & Building Energy
After watching this video, you should be able to explain what nuclear physics is, including the concept of binding energy. You should also be able to explain how fusion and fission work. A short quiz will follow.
7. Heisenberg Uncertainty Principle: Definition & Equation
The Heisenberg uncertainty principle is one of the core concepts in quantum mechanics. In this lesson, we define the uncertainty principle and learn more about its implications for physical science.
8. 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.
9. 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.
10. Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction
When a radioactive particle gives off radiation, what happens to the particle? This lesson will explain the three major types of radiation and what effect they have on the decaying atom.
11. 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.
12. 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.
13. 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.
14. Disintegration Energy in Nuclear Physics: Definition & Formula
After watching this video, you should be able to explain what disintegration energy is and use mass-energy equivalence to calculate the disintegration energy in a nuclear decay reaction.
15. Electron Cloud: Definition, Model & Theory
Like the rapidly moving blades of a fan, electrons appear to occupy all of the space in an atom at once. Learn how electron location in an atom is best described by the electron cloud model and theory.
