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....

Einstein's Revolution: Crash Course History of Science
There was physics before Einstein in the same way that there was biology before Darwin. Einstein didn’t just add some new ideas to physics. And he didn’t just add a unifying framework for doing physics, like Newton. Einstein took what...

TED-Ed: The surprisingly long history of electric cars | Daniel Sperling and Gil Tal
By the end of the 19th century, nearly 40% of American cars were electric. But these vehicles had a few major problems — early car batteries were expensive and inefficient, and the vehicles were twice the price of a gas-powered car. And...

Spectra Interference: Crash Course Physics
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!...

Matter as a Particle
In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

Transverse and Longitudinal Waves
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...

TED-Ed: Light waves, visible and invisible - Lucianne Walkowicz
Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our...
