1. 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.
2. 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.
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.
4. Neils Bohr: Discovery & Biography
Read about one of the most important contributors to modern physics, Niels Bohr. The Danish scientist led a fascinating life devoted to science, but also to peace after escaping Nazi-occupied Europe in the 1940s.
5. 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.
6. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table
Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.
7. Quantum Physics: Definition, Theories & Topics
While exploring this lesson, you will learn what quantum physics, otherwise known as quantum mechanics, is, examine some of its theories and topics, and discover the weird consequences that go along with it. A short quiz will follow.
