Description:
Sometimes in Physics is possible to find definitions that, trying to simplify the most, mislead instead of clarify. That happens when defining light, where you can easily find wrong definitions. Light behaves sometimes like a wave, and sometimes like a particle, with the oddness that, when behaving as a particle, its energy depends on the frequency defined by the non-compatible wave model. Anyway, light comprise both wave and particle characteristics together, but not as a simple addition; it is something more. However, the lack of a precise definition has not been an impediment for the creation of a number of devices by the modern technology such as lasers, optical fibers, micro video cameras or the recent plasma TV. Many other models have been tried, some of them very sophisticated, but at e moment no one has worked satisfactorily.
