Are red light and infrared light the same?

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.


Is ultraviolet light visible?

No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.


What is the light that is not visible 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


What energy in the form of electromagnetic radiation most often associated with a wavelength that is visible to the eye?

Visible light is the energy in the form of electromagnetic radiation that is most often associated with a wavelength that is visible to the human eye.


Is red the longest wavelength of light visible to the human eye?

Yes, that's correct.


What are facts on light?

light (electromagnetic radiation of a wavelength that is visible to the human eye (about 400–700 nm))


Is red is the longest wavelength of light visible to the human eye?

The red end of the spectrum. Red has lower frequency, lower energy and longer wavelength than the blue end of the spectrum.


What does Wave length 650nM means?

A wavelength of 650nm refers to light in the red part of the visible spectrum. This wavelength corresponds to a specific color of light that is visible to the human eye.


Does UV have a longer wavelength or visible light?

Infrared has a smaller wavelength than microwaves.


Which form of light cannot be seen?

Ultraviolet light cannot be seen by the human eye as it has a shorter wavelength than visible light.


What is difference between visible and infrared light?

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.


A wavelength just outside the visible red wavelength is?

Infrared light has a wavelength just outside the visible red wavelength. This type of light is longer in wavelength than red light, making it invisible to the human eye but detectable by special cameras or sensors.
