Fényenergia is the Hungarian term for light energy. It refers to the energy carried by electromagnetic radiation, specifically visible light. Light energy is a fundamental aspect of the universe and plays a crucial role in numerous natural processes. It is produced by sources like the sun, stars, and artificial lighting.

The concept of light energy is closely tied to physics, particularly the study of electromagnetism and quantum mechanics. Light travels in discrete packets of energy called photons. The energy of a photon is inversely proportional to its wavelength, meaning shorter wavelengths correspond to higher energy photons. This is why ultraviolet light, which has a shorter wavelength than visible light, can be harmful, while infrared radiation, with longer wavelengths, is perceived as heat.

Photosynthesis, the process by which plants convert light energy into chemical energy, is a prime example of light energy's importance for life on Earth. Solar panels utilize photovoltaic technology to capture light energy and convert it into electricity, demonstrating its application in renewable energy generation. Understanding and harnessing light energy has led to significant technological advancements and continues to be an area of active research.
