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...

Using Sunlight to Propel Spaceships
When scientists are planning missions, they sometimes have to take into account the fact that the light from the Sun pushes on the spacecraft. But with solar sails, they can also use that pressure to propel the craft along.

Wave Superposition
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...

What is the Uncertainty Principle
In this episode, we talk about the Heisenberg uncertainty principle and how it's not really that weird - it's just a property of waves!

Wave Equation
In this video Paul Andersen explains how a sine or cosine wave can describe the position of the wave based on wavelength or wave period. A wave function can the position of a wave as a function or the amplitude and wavelength or the...

Beats
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...

Wave-Particle Duality of Light
In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...

Light Is Waves: Crash Course Physics
The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know...

How Do Polarized Sunglasses Work?
The useful glare-blocking properties of polarized sunglasses are well-known to just about anyone who goes outside. What isn't so well-known is how they reduce glare in the first place. That answer is deceptively complicated!

Diffraction Effects
In this video Paul Andersen explains how diffraction can be affected by the size of the wavelength. When waves pass through an opening or move around an obstacle a shadow region is created. The size of the shadow zone will decrease as...

Electromagnetic Radiation
In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...

Wave Diffraction
In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

Specular Reflection
In this video Paul Andersen explains how light that is perfectly reflected creates specular reflection. The angle of the incident ray is equal to the angle of the reflected ray. Specular reflection is also known as mirror-like...

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. ...

Interference Patterns
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 that...
