The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c," or light speed. According to physicistAlbert Einstein'stheory of special relativity, on whi...
You can see light, with its colors, intensity, reflection, refraction, focusing, and its characteristic of traveling along a straight line in a homogenous material; but you probably have no intuition for the physical nature of light, what it is made of, and how it works. In this chapter ...
Based on optical phenomena, such as interference, diffraction, and scattering, light exhibits wave-like behavior, whereas according to other phenomena, such as light traveling in straight lines and the photoelectric effect, light behaves like a particle1. The debate on whether light is a wave or...
