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
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.
Red is the longest wavelength of visible light
Red light has the longest wavelength of all the visible light colors.
A shorter wavelength of visible light corresponds to higher energy and a bluer color, while a longer wavelength corresponds to lower energy and a redder color.
Red light has the longest wavelength within the visible spectrum.
House lights radiate energy as electromagnetic waves in the wavelength bands of heat and visible light.
Different wavelengths of light have different colors.
The shorter the wavelength (blue rather than red), the higher the energy.
Red is the longest wavelength of visible 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.
Red light has a longer wavelength compared to blue light in the visible electromagnetic spectrum.
Red is the longest wavelength of visible light
Red light has the longest wavelength of all the visible light colors.
Infrared has a longer wavelength, and a lower frequency, than visible 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).
No, red light has the longest wavelength within the visible light spectrum.
No, red light has the longest wavelength within the visible light spectrum.
