The longest wavelengths visible to the average human being are in the range of ~700 nanometers which appears to be red to the human eye.
However, I am capable of perceiving the red light that my 2 Logitech cordless laser mice emit at 848 nanometers. I hope I am not damaging my eyesight, but I don't believe the emission spectrum for such a laser would be very wide, so I would bet that 800-820 nm is still in the visible range, at least for younger people. I am 22 years old.
the longest wavelengths of visible are red colored

For a human, the frequency of the visible light range is 380 to 750 nanometers. Most people are around this range; some may able to see colors slightly above or below this range.

What color of visible light has the longest wavelength?
Red is the longest wavelength of visible light
Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
The shorter the wavelength of visible light means what?
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
Does infred waves have the same wavelength as visible light waves?
Infrared radiation is not visible. Its wavelength is longer than red.
A wavelength just outside the visible red wavelength is?
The wavelength is .8 microns or 800 nanometers.
What form of energy in energy of house lights?
House lights radiate energy as electromagnetic waves in the wavelength bands of heat and visible light.
Is color a characteristic of visible light that does not depend on the lights wavelength?
Different wavelengths of light have different colors.
How do wavelengths of visible lights relate to energy?
The shorter the wavelength (blue rather than red), the higher the energy.
What color of visible light has longest wavelength?
Red is the longest wavelength of visible light
What color of visible light has the longest wavelength?
Red is the longest wavelength of visible light
Which end of the visible electromagnetic spectrum has longer wavelength Red or Blude?
Deep dark red is the visible light with the longest wavelength. Violet is the visible light with the shortest wavelength.
What is longer than visible wavelength called?
Infrared has a longer wavelength, and a lower frequency, than visible light.
Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
The shorter the wavelength of visible light means what?
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
Is a red light a visible light with the shortest wavelength?
No, red light has the longest wavelength within the visible light spectrum.
Does infred waves have the same wavelength as visible light waves?
Infrared radiation is not visible. Its wavelength is longer than red.
Is the Visible light with the shortest wavelength a red light?
No, red light has the longest wavelength within the visible light spectrum.
