Lichtspektrum

Lichtspektrum refers to the range of electromagnetic radiation that is visible to the human eye. This visible portion of the electromagnetic spectrum is a small segment of the broader spectrum, which includes radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. Light itself is composed of photons, which are elementary particles that carry electromagnetic force. The different colors we perceive correspond to different wavelengths of light. Violet light has the shortest wavelengths, while red light has the longest. The order of colors in the visible spectrum, from shortest to longest wavelength, is commonly remembered by the acronym ROYGBIV: red, orange, yellow, green, blue, indigo, and violet. When white light, such as sunlight, passes through a prism, it is dispersed into its constituent colors, revealing the full visible spectrum. Different light sources emit different spectrums. For example, incandescent bulbs produce a continuous spectrum, while fluorescent lights and LEDs emit more discrete spectral lines or bands. The study of light spectrums, known as spectroscopy, is crucial in many scientific fields, including astronomy, chemistry, and physics, for identifying substances and understanding physical processes.
