I have been an adult volunteer for the Boy Scouts of America since 2007. After my son earned the Eagle Scout rank and aged out of Scouting, I stayed involved to teach the Space Exploration merit badge class.
I became involved with Scouting in 2014, when my son joined a local troop in Lafayette. It was easy to reason that I was there as his chauffeur, but really I was thinking, “Why should he have all the fun?”
More than two thousand science and STEM educators participated in the first Science Educators' Best of Show™ Awards by casting their votes for products that they felt impacted science learning.
Similar to many scientific concepts, spectroscopy developed as a result of the cumulative work of many scientists over many decades. We typically credit Sir Isaac Newton with the development of spectroscopy,
Most people have used a microscope at some point during their education, but not everyone has used a spectroscope or spectrometer. While they share similar names, spectroscopy and microscopy are used for different purposes.
Spectroscopy is used for physical and analytical chemistry to detect, determine, or quantify the molecular composition of a sample.
When we consider what defines sound in a physics context, it can be tempting to assume sound is basically vibrations. While partially true, sound is much more complex than simple vibrations.
So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.
