What is another word for visible light?
Pronunciation: [vˈɪzəbə͡l lˈa͡ɪt] (IPA) 
Visible light refers to the portion of the electromagnetic spectrum that is visible to the human eye and ranges in wavelength from violet (400 nm) to red (700 nm). However, there are many synonyms for visible light, including optical radiation, colored light, discernible light, spectrally visible light, and daylight spectrum radiation. Each of these terms describes the same phenomenon but emphasizes different aspects of visible light, such as its wavelengths, colors, or visibility to the human eye. Whether we refer to visible light as optical radiation or daylight spectrum radiation, we can all appreciate its importance for illumination, color perception, and photosynthesis in plants.
