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
What else can I help you with?
Wavelength of electrons are what percent visible in the white light?
The wavelength of electrons is about 10,000 times shorter than the wavelength of visible light. This means that electrons are not visible in white light as their wavelengths are outside the visible spectrum.
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.
Which color of invisible light has the shortest wavelength?
Violet light has the shortest wavelength of the visible spectrum.
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
Wavelength of electrons are what percent visible in the white light?
The wavelength of electrons is about 10,000 times shorter than the wavelength of visible light. This means that electrons are not visible in white light as their wavelengths are outside the visible spectrum.
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 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.
What is longer than visible wavelength called?
Infrared has a longer wavelength, and a lower frequency, than visible light.
True or false visibe light with the shortest wavelength is red light?
No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).
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.
What colour light has the lowest wavelength?
Violet light has the lowest wavelength in the visible light spectrum.
