They work, for instance, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation.
Share. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. It ranges in wavelength from approximately 400 nm (4 x 10 -7 m) to 700 nm (7 x 10 -7 m). It is also known as the optical spectrum of light. By Andrew Zimmerman Jones.
Long Wavelength Visible Light is the Red visible light. The wavelength of the Red visible light ranges from the 625 nm to the 750 nm. The Smallest Wavelength Visible Light is the Violet visible light. The violet visible light has wavelength which ranges from 380 nm to 435 nm.
