WebIt travels fast, bouncing off objects and changing direction. This is called reflection. Some surfaces and materials reflect light really well. We call these reflective materials, and they can be very useful - for instance, wearing a hi-vis jacket while cycling in low-light will make you more visible. Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The first extant recorded examination of this subject was in ancient Greece. The ancient Greeks, Arabic scholars, and classical European scientists long debated this until Rømer provided the first calculation of the speed of light. Einstein's Theory of Special …
WebThe speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space. Visible light can also travel through certain types of glass, plastics, water, and other materials.
A light-yearis the distance that light can travel in one year — about 6 trillion miles (10 trillion kilometers).
