Colors, a variation of the wavelength of light they emit, is the focus of a video that explains the different frequencies of light waves, models how our brain processes the electromagnetic radiation, and how we perceive light.

Viewers learn about both natural and synthetic radiation in a video that discusses background radiation from cosmic rays, as well as from radioactive waste, radioactive fallout, and x-rays. It concludes with an explanation of alpha,...

We know that sound cannot be heard in space, but can space make sound? Artists use various techniques to turn radiation waves, the earth's magnetic field, and other scientific data into music. This is the 20th video in a series of 22.

Light waves are not equal. The video introduces the electromagnetic spectrum and describes the progression of the wavelength. It also highlights the visible light spectrum. 

How are the wavelength, frequency, and speed of a wave related? The instructor in the video explains the process of determining the frequency of a wave with a known speed and wavelength. The wave is then classified along the...

When your smartphone tells you the weather of your current location or gives you directions to the nearest gas station, there's more going on that you might realize. Follow along with this short video as it explains how...

What do quantum mechanics and global warming have to do with each other? More than you might think. Surprisingly, this video explains how it's not the energy emitted from the sun that causes the problem, but how the infrared radiation...
