Visible light consists of wavelengths of approximately what range?

Visible light is the range of electromagnetic radiation that is detectable by the human eye, which spans wavelengths from approximately 400 nanometers to 700 nanometers. This range encompasses the colors we see, from violet at the lower end to red at the higher end.

Selecting the option that states 300-750 nanometers captures this understanding, as it accurately includes the full spectrum of visible light. While the lower limit of 300 nanometers includes ultraviolet light, and the upper limit of 750 nanometers extends towards infrared, the key aspect is that the range encompasses the entirety of visible light wavelengths we perceive.

Understanding this range is crucial in psychology, particularly when discussing perception, as it highlights how our sensory systems are tuned to specific wavelengths, allowing us to interpret the world visually. The specific range of visible light has implications in diverse areas, including art, design, and even therapeutic practices, revealing our cognitive responses to color and light.
