Light is more than what we see. The Sun sends out a number of waves of light in different wavelengths. Find out about wavelengths and the electromagnetic spectrum. Science Trek is available to stream ...

Due to how light travels, we can only see the most eye-popping details of space—like nebulas, supernovas, and black holes—with specialized telescopes. Electromagnetic Spectrum: the visible range ...

In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves ...

A team of engineers built a system that lets people to see colors in the infrared spectrum — as long as they’re looking through a camera lens. The team says that the device can be used to image gases ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...
