Light travels only one way: in a straight line. But the path it takes from Point A to Point B is always a waveform, with higher-energylighttraveling in shorter wavelengths.Photons, which are tiny parcels of energy, have been traveling across the universe since they first exploded from theBi...

The word “light-year” comes from the Danish word for “year,” and refers to the time thatlighttakes to travel a certain distance. The term is often used to refer to the distance thatlighttravels, rather than to the length of the distance. The term is sometimes misused as a time uni...
Light travels from themoonto our eyes in about 1 second, which means the moon is about 1 light-second away. Sunlight takes about 8 minutes to reach our eyes, so thesunis about 8 light minutes away. Light fromAlpha Centauri, which is the nearest star system to our own, requires roughly...
How does light slow down? Yes, the speed of light is always a constant. But it slows down whenever it travels through a medium like air or water. How does this work? There are a few different ways to present an answer to this question, depending on whether you prefer a particle-like...
The question of how light travels through space is one of the perennial mysteries of physics. In modern explanations, it is a wave phenomenon that doesn't need a medium through which to propagate. According to quantum theory, it also behaves as a collect
