Fotonjelenségek

Fotonjelenségek refers to observable phenomena involving photons, the fundamental particles of light. These events are central to our understanding of electromagnetism and the quantum nature of light. Key examples include reflection, where light bounces off a surface, and refraction, where light bends as it passes from one medium to another. Diffraction showcases the wave-like properties of light, causing it to spread out when encountering an obstacle or aperture. Interference demonstrates how waves of light can combine, either constructively to increase intensity or destructively to decrease it. The photoelectric effect is a crucial quantum phenomenon where light incident on a material can eject electrons, proving that light energy is quantized into discrete packets called photons. Compton scattering involves the inelastic scattering of photons by charged particles, typically electrons, resulting in a change in the photon's wavelength.
