One of the essentials for this year is chemistry and one of the things that we learn about in chemistry is emission. During the period we learn how different reaction between flame and salt give a different color. After the session, we did a mini experiment and this what we found.

Wavelengths of light (in NM) (quantitative)

Barium Chloride Yellow 570
