How Black can VantaBlack be?

How Black can VantaBlack be? Any student of Physics knows that black surfaces are good absorbers of radiation of the visible and the infrared spectrum of light—they readily soak in visible light and heat rays. That is the reason they look black, as they reflect very little light. In fact, the amount of light reflected by a black surface is a measure of its blackness. Therefore, when VantaBlack, from the UK-based Surrey NanoSystems, is called blacker than black, there is a specific reason—it Read more [...]

What is Infrared?

What is Infrared? The electromagnetic spectrum has waves of various wavelengths. Human eyes are capable to seeing the light that form a small part of electro magnetic spectrum. The waves with shorter wavelength as well are longer wavelengths than the visible spectrum are not visible. Infrared are waves that have longer wavelengths than the visible spectrum. The wavelengths corresponding to the Infrared waves are in between 750nm to 1mm. Infrared waves cannot be seen but can be felt in the Read more [...]
