Harmonics
In this video Paul Andersen explains how the wavelength of a standing wave is determined by the boundary length and frequency of the wave. The fundamental frequency has a wavelength double the boundary length. Harmonics are built on the...

Standing Waves
In this video Paul Andersen explains how standing waves are created through the reflection and interference of traveling waves. Destructive interference creates areas of no movement called nodes. Constructive interference creates areas...

Traveling Waves
In this video Paul Andersen explains how traveling waves move through space and time. The reflection and interference of traveling waves can create standing waves which appear motionless. Examples of traveling waves in one and two...

What are the Strings in String Theory?
Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what's all this nonsense of extra dimensions?

Wave Interference
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. ...

Rubens' Tube
We create a Rubens\u2019 Tube to demonstrate the movement of sound waves. A tube lined with holes is filled with propane and connected to a speaker. We light the gas coming from the holes and play different frequencies and volumes of...

Quantum Mechanics and the Schrodinger Equation
Okay, it's time to dig into quantum mechanics! Don't worry, we won't get into the math, we just want to understand what the math represents, and come away with a new and improved view of the electron as both a circular standing wave and...

Stringed Instrument Frequencies
The equation for the harmonic frequencies of stringed instruments is derived. Harmonic numbers and fundamental frequency are defined. A guitar is used to demonstrate harmonic numbers.

Singing plates - Standing Waves on Chladni plates
Use physics to create cool patterns on a vibrating plate. How is this like a guitar string or a singing wine glass?

How Is This Standing Wave Possible?
When standing waves are allowed at 15, 30, and 45 hertz on a string, then we should not see a standing wave pattern at 22 hertz. Yet, we do in this demonstration. This explains why.

Standing Waves and Harmonics
Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better...
