optikës
Optikës (optics) is the branch of physics that studies light and its interactions with matter. It examines how light is generated, how it propagates through space and media, and how it is detected and used by eyes and instruments. The field covers phenomena such as reflection, refraction, dispersion, diffraction, interference, and polarization, as well as imaging and the design of optical devices. Modern optics includes quantum, nonlinear, and computational aspects that describe light at small scales and in complex environments.
Historically, optics progressed from practical concerns about vision and measurement to fundamental theories. Early contributions by
Key concepts include the speed of light in vacuum, c, and the refractive index; Snell’s law for
Applications of optikës include corrective eyewear, cameras and imaging systems, telescopes and microscopes, lasers in industry
