Light sometimes appears to be "dragged" by the motion of the medium through which it is traveling. This phenomenon, referred ...

Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave.

In transverse waves like light, the vibrations are perpendicular to the direction of wave propagation. In longitudinal waves like sound, the vibrations are parallel to the direction of wave ...

Researchers have identified unexpected dynamic properties of a type of light wave called evanescent waves. These surprising findings contrast sharply with previous knowledge about light and photons.

Light is also this kind of wave, with the magnetic and electric effects zig-zagging, growing one way, then shrinking, growing the opposite way, shrinking again, and so on, transverse to the ...
