Visible light passes through a glass prism and creates a rainbow on the wall.
Definition
Noun: 1. Electromagnetic radiation perceptible to the human eye: A specific range of electromagnetic radiation with wavelengths approximately between 380 and 750 nanometers, which stimulates the retina and is perceived as sight, enabling the visual perception of the world.
Examples of Usage
- Noun:
- Sunlight is composed of many types of radiation, including ultraviolet, infrared, and visible light. (The portion of sunlight we can see.)
- A prism separates white visible light into its constituent colors, creating a spectrum. (Demonstrating the component colors within the visible range.)
- Some animals, like bees, can perceive ultraviolet light, which is outside the range of human visible light. (Contrasting with other parts of the electromagnetic spectrum.)
Advanced Usage
- "The visible light spectrum": The ordered array of colors (red, orange, yellow, green, blue, indigo, violet) that constitutes visible light, arranged by wavelength or frequency.
- Red has the longest wavelength in the visible light spectrum, while violet has the shortest.
Variants and Related Words
- Light (n): While often used synonymously in everyday language, "light" can refer more broadly to electromagnetic radiation of any wavelength (e.g., radio waves, X-rays) in scientific contexts, or to a source of illumination. "Visible light" specifies the portion relevant to human vision.
- Visible spectrum (n): A term often used interchangeably with "visible light," emphasizing the range of wavelengths.
- Photopic vision (n): The type of vision mediated by cone cells in the eye, which is responsible for color perception under normal visible light conditions.
Synonyms
- Light (in its common, non-scientific sense)
- Visible radiation
Related Phrases
- Visible light transmission (VLT): A measurement of the amount of visible light that passes through a material like a lens or window.
- Sunglasses with a low visible light transmission percentage are darker and block more light.
