Observing Flames and Specs through a Spectroscope

Spectroscopy is the study of the interaction between matter and radiated energy. English philosopher Roger Bacon(1214-1294) was the first person to recognize that if sunlight passes through water it splits into colors. Around four centuries ago, Isaac Newton originated the title “spectrum” to label the shade of rainbows put together by transferring sunlight through a prism. William Hyde Wollaston(1766-1828) was an English chemist physicist. He came up with some important advancements in solar physics, he discovered the spectrum of sunlight is crossed by a number of dark lines.
Materials and Methods
For this project my group and I used a Bunsen burner to light the gas up. A Bunsen burner, named after "Robert Bunsen", is a lab piece equipment that produces a single flame which is used for heating,sterilization and combustion. Our instructor, Dr. Immel, provided us with six heavy metals those metals were: Barium, Calcium, Lithium, Potassium, Sodium, Strontium. My group got a platinum flame loop, and decontaminated it with the water beaker filled half way with water. To light the Bunsen burner my group used a striker, which Dr. Immel provided. We started off with Barium, when Charlotte put it into the flame it gave the flame a yellow kind of color and a sprinkle of green. After we decontaminated the loop, we moved onto calcium. Calcium gave the flame an intense orange, it was extraordinary. After that, we got to Lithium, Lithium gave the flame an intense red. The next metal is Potassium, it gave the flame a light purple, which kind of resembled white. Sodium was a unique one, giving the flame an orange look, resembling the original flame color. It was very hard to tell the difference. The last of the metals is Strontium, which gave the flame a red color and switched very fast over...
