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 ...

Color is determined by a wavelength, your eyes, and your brain. What are light and color? It all starts with the Sun. The Sun puts out a lot of different waves of light, some of which we can see ...

Infrared light has longer wavelengths than visible light, and we can feel it as heat. In fact, some animals, like snakes, can see in the infrared part of the spectrum! Visible light is what we can see ...

The debate over whether light behaves as a wave or a particle goes all the way back to the 17th century, when two titanic figures in physics history took opposite sides on the issue.

The color of the sky depends on scattering light particles. ... Light travels in waves—sometimes in short, dippy ones and other times in long lines with lots of peaks.

During a total solar eclipse, people may see some strange things. Sure, there’s the main event happening in the sky (SN: 1/4/24).But the world may also look a little different on the ground.

Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to ...

The scientists sent pulses of light around the edges of these 2D materials using a ultrafast transmission electron microscope (UTEM), which produced within it hybrid sound-light waves.
