Prism-coupling refractometry
Okay kiddo, have you ever played with a toy prism? It's a triangular piece of glass or plastic that splits white light into a rainbow of colors, right? Well, scientists use something similar called a prism-coupling refractometer to measure how light bends when it enters a new material, like glass or plastic.
They shine a really thin beam of light onto the surface of the material and watch how it bends or refracts. The angle that the light bends tells them how much the material slows down the light, and that's called the refractive index.
The refractive index is important because it tells scientists how light will behave when it travels through different materials, like when it goes from air into water or from glass into your eyes. So, by measuring the refractive index, scientists can learn more about how different materials work and how they interact with each other.
Pretty cool, huh? And all of this is possible thanks to a little toy prism that you might have in your toy box!
