Spectral band

Imagine you are listening to a song and the singer's voice sounds different than the guitar playing. This is because the sound waves that make up the singer's voice and the guitar are different from each other.

In a similar way, when we talk about light (which is just another type of wave!), we can separate it into different colors. We do this by looking at the different wavelengths (or sizes) of the waves that make up the light.

Each color of light has a different wavelength, and we can group certain wavelengths together to create "spectral bands." It's like putting different colored marbles into different jars - the marbles in each jar are similar to each other, and different from the marbles in another jar.

Scientists use spectral bands to study different things in our world, like plants and oceans. By looking at the different wavelengths of light that are reflected or absorbed, they can learn a lot about what's going on in that particular area. It's like being able to look at the colors of the world around us in a really detailed way!
