You're welcome to submit questions to one of our instructors through the Dashboard.
1. 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.
2. What is Scattering? - Definition & Examples
In physics, it's rare for wave energy to travel in a completely straight line. Several processes can occur that make the wave depart from its path. This lesson will cover one of those processes, scattering, and give a few examples of it in action.
3. Frustrated Total Internal Reflection
Under certain conditions light that should be reflected in total internal reflection can be refracted instead. This process is known as frustrated total internal reflection, and in this lesson we will learn how it works.
4. Thin Lens Equation: Examples & Questions
After watching this lesson, you will be able to explain what a lens is (both concave and convex), list uses of lenses in everyday life, and use the thin lens equation to solve problems. A short quiz will follow.
5. Ray Diagrams & Lenses: Physics Lab
After completing this lab, you will be able to explain how lenses work, explain the difference between convex and concave lenses, draw ray diagrams to analyze the image produced by a lens, and apply that understanding to eyeglasses.
6. Reflection: Angle of Incidence and Curved Surfaces
How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.
7. Plane Mirror: Definition & Uses
Imagine a world without mirrors. The way we conduct our lives would be very different. Would we have different views on the way we look? How would we know what was behind us while driving? In this lesson, we'll talk about plane mirrors and their uses.
8. What is a Concave Mirror? - Definition, Uses & Equation
A concave mirror can make images that appear to float in the air! In this lesson, you will learn about what concave mirrors look like and how they work.
9. Using Equations to Answer Mirror Questions
After watching this lesson, you will be able to answer questions on mirrors, stating whether an image is real or virtual, upright or inverted, and larger or smaller. A short quiz will follow.
10. The Doppler Effect: Definition, Examples & Applications
What is the Doppler effect? How does it affect our perceptions of sound and light? In this lesson, learn how traveling wave sources can change the way we observe sound and light waves. Explore the applications of the Doppler effect on shock waves, sonic booms, and the movements of distant galaxies.
11. 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.
