1. What is the Law of Reflection of Light? - Definition & Overview
In this lesson you will learn about the concept of reflection, including one of the simplest laws of physics, the law of reflection. You will learn about the main features of the law of reflection as well as some application and facts about reflection in general.
2. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction
Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.
3. Lens Types: Simple, Compound & Other Types
In this lesson we will explore what a compound lens is versus a simple lens as well as what it means for a lens to be concave or convex and how these particular lens shapes can be used to correct certain visual impairments.
4. Mirrors: Difference Between Plane & Spherical
After watching this lesson, you will be able to explain what a mirror is and how plane mirrors and spherical mirrors are different, including the images they produce. A short quiz will follow.
5. How Telescopes Form Images
This lesson will explain to you the fundamental points of how images are formed in refracting and reflecting telescopes as well as why our eyes need telescopes to help us see distant objects.
6. Microscopy Types & Applications
What is microscopy and how do we use it? Learn about the different types of microscopes and the ways we use them for practical purposes. You can then take a quiz and test what you've learned.
7. Diffraction & Huygen's Principle
After watching this video, you will be able to explain what diffraction is, provide some real-life examples of diffraction, state Huygen's Principle, and explain how Huygen's Principle applies to those real-life examples. A short quiz will follow.
8. Single-slit Diffraction: Interference Pattern & Equations
After watching this lesson, you will be able to explain what single-slit diffraction is, describe and picture the pattern that it creates on a distant screen and use the equation of single-slit diffraction to solve problems. A short quiz will follow.
9. Double-slit Diffraction: Interference Pattern & Equations
This lesson explores double-slit diffraction, including the significance of Young's double slit experiment and how the diffraction pattern forms. You will also learn to use equations to calculate the positions of minima and maxima in the pattern.
10. How Thin Film Interference Works
After watching this video, you will be able to explain how thin film interference works, give examples of thin film interference in everyday life and solve simple problems. A short quiz will follow.
11. Electromagnetic Waves: Definition, Sources & Properties
In this lesson, learn the basics of electromagnetic waves and how they make up the electromagnetic spectrum. We will explore the major trends and categories within the spectrum, as well as the various sources of electromagnetic waves.
12. The 7 Major Regions of the Electromagnetic Spectrum
This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.
13. Polarization of Light & Malus's Law
After watching this video, you will be able to explain what polarization of light is, list a number of examples of how polarization of light is used, state Malus's Law, and use it to solve problems involving the intensity of light through a polarizer.
14. Polarization by Reflection & Brewster's Law
After watching this lesson, you will be able to explain what polarization by reflection is, give a few examples of polarization in everyday life, explain Brewster's Law descriptively and use the equation to solve problems. A short quiz will follow.
