How does light energy travel
WebSep 6, 2024 · Light is a type of energy that travels through the air and interacts with matter. When light hits an object, it can do one of three things: it can be absorbed, reflected, or transmitted. The color of light depends on its wavelength. Red light has a longer wavelength than blue light, for example. WebWhen they travel through empty space, one might expect that there is no mechanism by which they can lose energy. Actually, however, there is one way that photons do lose energy as they travel through space. Because the universe is expanding, the photon's wavelength increases very slightly over time, and in so doing loses a bit of energy.

WebJul 16, 2024 · All light shares three properties. It can travel through a vacuum. It always moves at a constant speed, known as the speed of light, which is 300,000,000 meters (186,000 miles) per second in a vacuum. And the wavelength defines the type or color of light. Just to make things interesting, light also can behave as photons, or particles. WebWhen a light wave with a single frequency strikes an object, a number of things could happen. The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be …
