Balmer series

When you look at light through a prism, you can see all the colors of the rainbow. But there are some special colors of light that scientists call the "Balmer series."

These colors of light are special because they come from a type of gas called hydrogen. When hydrogen is heated up or excited, it gives off these specific colors of light.

The Balmer series is a sequence of colors that are all related to each other. They start with red light, then go to blue-green, blue, and finally purple. These four colors make up the Balmer series.

Scientists can use the Balmer series to learn more about hydrogen gas and how it behaves. By studying the exact colors of light that hydrogen gives off, they can learn things like the temperature and pressure of the gas.

So, the Balmer series is really just a fancy way of talking about some special colors of light that come from hydrogen gas. And scientists use these colors to learn more about the gas and how it works.
