The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

Blue light is a high-energy light that the eyes absorb from computers, smartphones, LED lights, and fluorescent lights. The sun is the biggest source of blue light. On a sunny day, it's 100,000 ...

The discovery, made with the LOFAR (LOw Frequency ARray) radio instrument in Europe, indicates that galaxy clusters, which ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This ...

Blue light, which is low-wavelength and high energy, does behave differently on the eye, See says, and in large doses can cause harm to the retina. However, as Benner points out, screens are not a ...

Scientists have detected the highest-energy "ghost particle" ever seen. The particle, a type of neutrino, arrived at Earth at nearly the speed of light and with 30 times the energy of the previous ...

Blue light has very short, high energy waves. In fact, they’re only slightly longer and less powerful than UV waves, which are too short for people to see with the naked eye.

This high-energy light radiates from our smartphones, computer screens, tablets, LED lighting, and even the sun—which remains by far our most significant source of blue light exposure ...

A faint radio glow reveals a million-light-year halo enveloping one of the earliest galaxy clusters, hinting that energetic ...

The continuous development of bright, stable and highly coherent high-energy light sources is a propellant to the fields of material science, biomedical imaging, ultrafast spectroscopy, and ...

LOFAR is a massive radio telescope that comprises 100,000 antennas spread across eight European countries. The researchers ...
