It is literally called visible light..
The wavelength is too long to be seen by our eyes.
At a single wavelength, it is called monochromatic
Ultraviolet light cannot be seen by the human eye as it has a shorter wavelength than visible light.
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
The wavelength of infra-red light is LONGER than the wavelength of red light, and longer than anything to which the eye responds.
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
A spectral line
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
Electromagnetic radiation having a wavelengths between 380 - 750nm is visible to the normal human eye. This region of the spectrum is called visible light. Radiation of any other wavelength cannot be seen with the naked eye
When excited by 532 nm green light, caffeine has been seen to fluoresce in the 625 nm wavelength region. This is visible orange light.
Any light wave with a wavelength between roughly 350 to 750 nanometers.
