lysbølge

Lysbølge is a Danish term that translates to "light wave" in English. It refers to the fundamental way light behaves and propagates through space. Light exhibits wave-like properties, meaning it can be described by characteristics such as wavelength, frequency, and amplitude. These properties determine the color of visible light, as well as the nature of other forms of electromagnetic radiation like radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. The electromagnetic spectrum encompasses all these types of light waves, ordered by their wavelength and frequency. The concept of lysbølge is central to understanding phenomena such as diffraction and interference, where light behaves distinctly as a wave. While light also has particle-like properties (photons), the wave model is crucial for explaining many optical effects.
