The correct answer is: A. Visible, infrared, ultraviolet
Visible light has the shortest wavelength, followed by infrared light, and then ultraviolet light.
- Visible light has a wavelength of about 400 to 700 nanometers (nm).
- Infrared light has a wavelength of about 700 nm to 1 millimeter (mm).
- Ultraviolet light has a wavelength of about 10 nm to 400 nm.
Visible light is the only type of light that we can see with our eyes. It is what gives objects their color. Infrared light is invisible to the human eye, but it can be felt as heat. Ultraviolet light is also invisible to the human eye, but it can cause sunburn and skin cancer.
The order of the wavelengths of light is important because it determines how the light interacts with matter. For example, visible light can be absorbed by pigments in plants, which is how plants use sunlight to make food. Infrared light can be absorbed by water molecules, which is how we feel warm when we stand in front of a fire. Ultraviolet light can damage DNA, which is why it is important to wear sunscreen when you are in the sun.
