Whenever we open a new window on the universe we discover something new. Whether it's figuring out how to see to greater distances like with telescopes, or down to smaller size-scales like with microscopes, or perhaps expanding our...

Many Worlds interpretation of quantum mechanics proposes that every time a quantum event gets decided, the universe splits so that every possible outcome really does occur. But where exactly are those worlds, and can we ever see them?

The double slit experiment radically changed the way we understand reality. Find out what the ramifications of this experiment were and how we can use it to better comprehend our universe.

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

You're on a flight, and the drone of the engines is getting on your nerves, so you pop on a pair of noise-canceling headphones, and sweet, blessed silence descends. But those headphones aren't just muffling the sound -- they're actually...

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...

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...

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...

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!...

The effect that happens when two waves travelling through the same space meet.

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...

It describes linear combination of atomic orbitals, conditions for combination of atomic orbitals, types of molecular orbitals and energy level diagram.

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.

Overview of interference using the example of sound waves.

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