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

What wave lengths is closest to the wave length of red light?
Visible light wavelengths fill the electromagnetic spectrum between red wavelengths and violet wavelengths.
What is a form of energy with wavelengths that are longer than those of red light?
infrared light
Difference between infrared waves and red light waves?
Infrared waves have longer wavelengths compared to red light waves. The wavelengths of infrared waves are too long for the naked eye to see, while red light waves can be seen as part of visible light.
If an object absorbs all wavelengths of light except red what color will it appear?
The object will be red, due to the red light of the spectrum being reflected.
When a continuous spectrum of light passes through a red filter the red absorbs the red wavelengths true or fasle?
No, the red absorbs all the colors in the light exceptred.
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?
Red and Blue light look different because they have different wavelengths. Red has the longest Wavelength and Blue has a shorter wavelength than Red. Hope this helps :)
What wave lengths is closest to the wave length of red light?
Visible light wavelengths fill the electromagnetic spectrum between red wavelengths and violet wavelengths.
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 light
Difference between infrared waves and red light waves?
Infrared waves have longer wavelengths compared to red light waves. The wavelengths of infrared waves are too long for the naked eye to see, while red light waves can be seen as part of visible light.
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 be red, due to the red light of the spectrum being reflected.
