Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build...

The pigments in our food all get destroyed on their way through our digestive system...so where do the colors of our poop and pee come from?

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. ...

There are over one billion cars in the world right now, getting people from point A to point B. But cars aren't just a mode of transportation; they also teach an excellent lesson in chemistry. Cynthia Chubbuck navigates the intricate...

In this video Paul Andersen describes some of the properties of waves. He starts be identifying particles and waves as the only phenomenon that can transfer energy from place to place. He identifies the defining characteristics of...

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...

In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...

In this video Paul Andersen explains how the energy of a wave if directly related to the amplitude of a wave. The wave energy of a sound wave is the volume of the wave.

Mr. Andersen introduces the concept of waves. Both transverse and logitudinal waves are described. The relationship between wave speed, wave frequency and wavelength is also included.

Under the leadership of Lisa Jackson, Apple's environment and social VP and former head of the EPA, the company is already carbon neutral within their own corporate and retail boundaries. By 2030, Apple hopes to extend carbon neutrality...

In this video Paul Andersen compares and contrasts transverse and longitudinal waves. Waves carry energy through oscillations. In transverse waves the oscillations are perpendicular to the direction of the wave and in longitudinal they...

In this video Paul Andersen compares and contrasts mechanical and electromagnetic waves. Both types of waves transfer energy through oscillations but mechanical waves requires a medium. Several examples of each type of wave are included.

In this video Paul Andersen details the characteristics of electromagnetic waves. Electromagnetic waves are transverse waves that can move through both mediums and vacuums. The electric and magnetic fields oscillate perpendicular to...

In this video Paul Andersen explains how the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...

Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics,...

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 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...

This video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc. I want to see Cat LIGO ASAP!

The wave model of the electron can be used to explain the Bohr model. Electrons are found in certain orbits because they interfere with themselves and create standing waves. When the wavelengths don't match up with a whole integer they...

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

For a long time, rogue waves (defined as waves that are greater than twice the height of surrounding waves) were thought to be a myth, like mermaids or the kraken, but recent developments in satellite imagery and oceanic instruments now...

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...
