Scientists have developed reliable early warning systems for tsunamis caused by earthquakes. The problem is, earthquakes aren't the only things that cause tsunamis.

Sound waves vibrate more than just our eardrums, they can also make visual art!

In this video Paul Andersen explains how waves interact when moving through one another. Unlike particles waves can interfere both constructively and destructively. The amount of interference is determined through the superposition...

Can you feel them in your fingers? How about in your lungs? Vibrations are all around us, so let’s explore some everyday vibrations!

In this video Paul Andersen explains how beats are created through interference of waves with similar frequencies. The changes in amplitude are caused by destructive and constructive interference. The frequency of beats is equal to the...

In this video Paul Andersen explains how waves interact with objects and with other waves. When a wave hits a fixed object it will be reflected and inverted. When a wave hits a free object it will be reflected without being inverted. ...

In this video Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment...

Light is everywhere … but it’s not as predictable as you might think. It’s a wave that travels in straight lines, yet it also reflects off of surfaces, refracts through various materials, and generally changes direction all the time!...

Why Quantum mechanics applies to more than just the smallest particles. And how quantum mehcnaics converges to the classical limit depending on the de brogile wavelength.

We explore the double slit experiment and discover bucky...

Review of the Mechanical Waves topics covered in the AP Physics 1 curriculum.

Admittedly, my prior tutorial on MO theory was a little confusing, and had some errors. I wanted to make things right, so here's another one! This will clarify some of the basic concepts, and will also extend them to discuss a new...

When you hear the roar of traffic, the bark of a dog, or your teacher's voice, you are experiencing sound. This program uses colorful animations to explore important characteristics of sound, including intensity, loudness, pitch, and...

Reflection with and without inversion caused by fixed and free ends are demonstrated. Standing wave patterns at 5 different frequencies are demonstrated. A standing wave animation is shown to understand to how standing wave patterns are...

Bo teaches us about beat frequency. You get to hear what beats sound like, see the constructive and destructive interference wave forms, and learn a practical application of beats while tuning a guitar.

This video explores the concept of iridescence, where seemingly colorless or differently colored surfaces change their color when viewed from different angles. It explains how iridescence occurs through mechanisms like thin film and...

Light and sound waves do all kinds of cool stuff, because they can be in the same place at the same time, unlike matter. This creates patterns that are important to understand! Let's take a look.

The difference between wave and object interaction is demonstrated. Constructive interference, destructive interference, and total destructive interference via superposition are all demonstrated.
