we'd have night vision and we'd be sensitive to thermal radiation
There are colors outside of the visible spectrum that humans cannot see, such as ultraviolet and infrared. These colors are invisible to the human eye because our eyes are not sensitive to those wavelengths of light.
yes the human eye is sensitive to red 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.
Ultraviolet and infrared are colors that the human eye cannot see.
Ultraviolet and infrared are colors that the human eye can't see.
No, red light and infrared light are not the same. Red light has a longer wavelength and is visible to the human eye, while infrared light has a shorter wavelength and is not visible to the human eye.
Infrared is not a color, but rather a type of electromagnetic radiation that is invisible to the human eye.
Infrared light is not visible to the human eye, so it does not have a specific color that we can see.
The wavelength of infra-red light is LONGER than the wavelength of red light, and longer than anything to which the eye responds.
Yes, rods are more sensitive to light than cones in the human eye.
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
The human eye cannot see colors that are outside the visible spectrum, such as ultraviolet and infrared.
