examples of how light enery travels
First, in a game of flashlight tag, light from a flashlight travels directly from one point to another. Next, a beam of light is shone through a series of holes punched in three cards, which are aligned so that the holes are in a straight line. That light travels from the source through the holes and continues on to the next card unless its path is blocked.
Light energy is carried by photons which move at the speed of light. The energy can also be explained in terms of waves also moving at the speed of light. These explanations are equivalent. Light can be made up of different wavelengths mixed together, as from the sun. The nervous system perceives these different wavelength as different colors if the wavelengths are within the visible range. That is, color is not a physical property of light. It is the perception of a physical property of light.
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel ...
Light travels in electromagnetic waves through most spaces however in a vacuum it travels in a straight line. Light travels at approximately 299,792,258 meters per second. Some of light travel can be seen, some of it is invisible.
