Optiikkaalue

Optiikkaalue refers to the region of the electromagnetic spectrum that is visible to the human eye. This range typically spans from approximately 400 nanometers (violet light) to 700 nanometers (red light). Within this band, different wavelengths correspond to distinct colors, forming the spectrum of visible light that we perceive. The study of light and its behavior within this visible region, as well as its interaction with matter, is the core of optics, a branch of physics. Optical phenomena such as reflection, refraction, diffraction, and interference are all observable and studied within the optiikkaalue. Light in this range can be produced by various sources, including the sun, artificial light bulbs, and lasers. The human eye is specifically adapted to detect and interpret these wavelengths, allowing us to see the world around us. Understanding the optiikkaalue is fundamental to many scientific and technological applications, including the design of lenses, telescopes, microscopes, cameras, and display technologies.
