Wavelength of red light is about 700 nanometers. ie 700 x 10 to the minus 9 meters.
You may also come across units called Angstroms for light wavelengths-these were current when I was a physics student but went out of fashion. 1 Angstrom = 1/10 nm

Red light and white light reflect?
Red light reflects red wavelengths of light and absorbs other wavelengths. White light reflects all visible wavelengths of light.
Is red or violet light diffracted most?
Violet light is diffracted more than red light because shorter wavelengths are diffracted more than longer wavelengths.
As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the wavelengths of the light?
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm
Does red or violet have a longer wavelength?
Red light has a longer wavelength than violet light. Red light has wavelengths around 620-750 nanometers, while violet light has wavelengths around 380-450 nanometers.
What do humans see different wavelengths of as light?
Humans can see different wavelengths of light as different colors. Shorter wavelengths appear as violet and blue, while longer wavelengths appear as red and orange. The entire spectrum of visible light includes colors from red to violet.
Light energy with wavelengths longer than visible red?
Light energy with wavelengths longer than visible red is infrared light.
What is the wavelenghth of red light?
Red light has wavelengths in the range 622-780 nm.
Red light and blue light are different colors because the light that makes them up has different?
wavelengths. Red light has a longer wavelength than blue light, with red light having a wavelength around 620-750 nanometers and blue light around 450-495 nanometers. This difference in wavelength is what gives them their distinct colors.
What wave lengths is closest to the wave length of red light?
The wavelength closest to red light is around 620-750 nanometers, falling within the visible spectrum.
What wavelengths of visible light are not being absorbed by red and yellow pigment?
red and yellow
What happen when light pass through red glass?
All wavelengths of other colors of visible light are absorbed, only the wavelengths of red light will pass thru the glass.
Red light and yellow light have same speed?
Yes. Different wavelengths though.
What is a form of energy with wavelengths that are longer than those of red light?
Infrared radiation is a form of energy with wavelengths longer than those of red light. It is invisible to the human eye but can be felt as heat.
Difference between infrared waves and red light waves?
Infrared waves have longer wavelengths and lower frequencies than red light waves. Infrared waves are not visible to the human eye, while red light waves are a part of the visible spectrum. Infrared waves are typically associated with heat, while red light waves are perceived as a color.
Is red best for plant growth?
Red or blue light are the wavelengths of the visible light spectrum that are most absorbed by plants.
What determine the color of an object?
Light comes in many different "wavelengths". The wavelength of a beam of light determines its color.White light contains light of all different wavelengths, but objects can reflect of absorb different wavelengths.The light that an object reflects determines its color.In other words, an object that looks red must be absorbing all wavelengths of light except red.
If an object absorbs all wavelengths of light except red what color will it appear?
The object will appear red because it is reflecting the red wavelength of light and absorbing all other wavelengths.
