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
All of the electromagnetic spectrum can be reflected. White light is a combination of all colors. They all reflect, red is among them.
Beyond red are infrared wavelengths, and beyond violet are ultraviolet wavelengths.
Violet light is diffracted more than red light because shorter wavelengths are diffracted more than longer wavelengths.
No, the red absorbs all the colors in the light exceptred.
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.
Light energy with wavelengths longer than visible red is infrared light.

Violet light is diffracted more than red light because shorter wavelengths are diffracted more than longer wavelengths.
False. Visible light with the shortest wavelengths corresponds to violet and blue light, not red and orange. The visible spectrum ranges from approximately 380 nanometers (violet) to about 750 nanometers (red), with red light having the longest wavelengths.
No, the red absorbs all the colors in the light exceptred.
Red light has wavelengths in the range 622-780 nm.
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.
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm
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.
Red appears red when light falls on it because objects reflect certain wavelengths of light while absorbing others. In the case of red, the object reflects red wavelengths of light and absorbs other colors. This reflected red light is what our eyes perceive as the color red.
Red light has longer wavelengths than white light, which contains a mix of all visible wavelengths. Red light is at the longer end of the visible spectrum, while white light is a combination of all visible colors. Red light is often associated with warmth and relaxation, while white light is seen as neutral and bright.
