We know that not everyone's vision is perfect, which is why some of us need glasses. But some people can also just see more stuff than others! From seeing UV and infrared light, to even having bonus color receptors in our eyes, there are...

The world is full of colors. Almost all of them can be described by a wavelength of visible light, but there are some colors out there that are just in your head!

This week scientists invented futuristic technologies that sound made up by Hollywood’s spy movies, and we might be able to have infrared supervision without goggles...soon.

The Crab Nebula is one of the most studied things in the sky, but it took glimpses through various wavelengths of the electromagnetic spectrum to get a full picture of what’s hiding inside!

Besides the blue of the oceans, the dominant color of our planet, as we know it, is green. But imagine a time when the Earth looked a little .... purple.

Join Hank Green as he explains why blacklights make some things glow!

Since it launched in 1990, the Hubble Space Telescope has snapped more than a million images and changed the way we see the universe, literally.

The explanation covers the electron configurations, quantum mechanics, and relativistic effects that determine these properties. This video is perfect for anyone curious about the science behind element properties....

The light spectrum is the collection of colours that are generated when light is dispersed through a medium, such as a prism. This dispersion reveals the various wavelengths of visible light, with each wavelength corresponding...

NaCl, a perfect ionic crystal, has an alternating pattern of Na+ cations and Cl- anions. When heated, some Cl- anions can be lost, leaving anionic vacancies. These vacancies are occupied by electrons, creating F-centers, which are...

In a unique laboratory at the National Institute of Standards and Technology (NIST), vision scientists can simulate lighting from virtually any source, including incandescents, fluorescents or LEDs. With this capability, they can test...

How can you use an infrared camera to see through walls? To inspect the scene of a crime? To catch a thief in hiding?! This cool device attaches to your smartphone and has an infrared/visible light camera combo that allows you to see the...

This is a lecture video on the topic of wavelength and color. The video focuses on the visible light portion of the electromagnetic spectrum, which can be split into different colors. The video explains the relationship between...

This video provides a clear and concise explanation of how rainbows are formed through the reflection, refraction, and dispersion of sunlight by water droplets in the atmosphere. It also explores different types of rainbows, such as...

In this video, we explore the pathway for red blood cell destruction including the full degradation of heme b from the liver and spleen to renal and gastrointestinal elimination.

In this video, you will learn how rainbows are formed through the behavior of light waves. Sunlight, composed of different wavelengths, enters raindrops, causing the light to split into a multitude of colors. As the light refracts and...

This nugget explains the source, generation, properties and discovery of electromagnetic waves.

So we know that physics got turned upside down at the turn of the 20th century, but how did that all begin? What was the first thing that set this whole chain of events into motion? Well it all started with Planck and the ultraviolet...

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...
