15 Μαρ 2024 · Light travels through the vacuum of space at 186,828 miles per second as transverse waves, outside of any material or medium, because photons—the particles that make up light—also behave as waves. This is referred to as the wave-particle duality of light.
Learn about the straight-line motion of light, the speed of light, and the law of reflection. See examples, diagrams, and a quiz to test your knowledge.
24 Απρ 2017 · Learn how light is a form of electromagnetic energy that travels in waves without a medium, and how its speed and color depend on frequency and wavelength. Explore how light bends at interfaces and creates rainbows, and how Einstein's theory of relativity limits its speed.
21 Μαρ 2013 · This artist's animation depicts the "life" of a photon, or particle of light, as it travels across space and time, from the very early universe to the Planck satellite.
As the light from the universe’s most distant galaxies travels through space, it’s stretched by the expansion of space. By the time the light reaches Earth, that stretching process has transformed short wavelengths of visible and ultraviolet light into the longer wavelengths of infrared light.
Learn how light travels through different media, such as space, air, water, and glass, in this educational and entertaining video from YouTube.
19 Μαΐ 2016 · Learn about the history and theory of light, from ancient philosophers to modern physics. Discover how light behaves as both a particle and a wave, and how it travels at a finite speed in a vacuum.
