Okay kiddo, so imagine you have a really cool toy that can turn light into colors, just like a magic wand. That toy is called a prism spectrometer.
Now, let's say you have a flashlight and you shine it on the prism. The prism takes the light and splits it into different colors, just like a rainbow!
The way it does this is by bending the light at different angles depending on the color. So, red gets bent the least while violet gets bent the most. This is because each color has a different wavelength which affects how much it gets bent.
The prism spectrometer then takes those colors and measures how much of each color there is. It does this by shining the color through a special device that calculates the amount of light in each color.
Scientists love using prism spectrometers because they can use them to study different things. For example, they can use them to figure out what types of chemicals are in different materials, or to understand how stars and galaxies are made up of different elements.
Pretty cool, huh? The prism spectrometer is like a toy that grown-up scientists use to explore the world around us!
