Monochromatic radiation

Monochromatic radiation is when light shines in just one color or wavelength. Think of a rainbow, where all the colors of light are visible. Monochromatic radiation is like taking just one small slice of that rainbow, and only seeing one color. It's like when you use a colored marker to draw a picture, and only use that one color. Scientists use monochromatic radiation to study different materials, because they can see how the material reacts to just one color or wavelength of light. It's like looking at a piece of Lego under a microscope, and only seeing the little bumps and ridges that make up the plastic. Monochromatic radiation helps scientists to learn more about the world around us, and how different materials behave when they interact with light.
