Want this question answered?
Any wavelength shorter than roughly 400 nanometers, and any wavelength longer than roughly 700 nanometers, is invisible. That is, its presence is not detected by the human eye.
All wavelengths outside the range of 380 - 750nm are invisible to 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
Red is a color that is visible to the human eye, so it cannot be both red and invisible at the same time.
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.
It is an electromagnetic wave, which means it is similar to light, but invisible to the human eye. Infrared light (or infrared waves) have a longer wavelength and a smaller frequency than visible light.
Yes, that's correct.
Yes. EM Waves are not visible to 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.
The duration of The Invisible Eye is 1.58 hours.
