Fényhatás

Fényhatás is a Hungarian term that translates to "light effect" in English. It broadly refers to any perceptible visual alteration or phenomenon caused by the interaction of light with matter, or by the nature of light itself. This encompasses a wide range of occurrences, from simple reflections and refractions to more complex optical phenomena.

In physics, a fényhatás can describe how light bends as it passes from one medium to another, a principle known as refraction. It also covers the scattering of light, such as the blue appearance of the sky, which is a Rayleigh scattering effect. Rainbows are a spectacular example of a fényhatás, caused by the dispersion of sunlight into its constituent colors through water droplets.

Beyond natural phenomena, the term is also used in artistic and technological contexts. In art and design, a fényhatás refers to the deliberate manipulation of light and shadow to create mood, depth, or emphasis, often seen in painting, photography, and stage lighting. In technology, it can describe the visual effects generated by lighting systems, such as those used in entertainment or for decorative purposes. The term is versatile and can be applied to anything from the glint of sunlight on water to the intricate patterns created by specialized lighting equipment.
