Here is the much awaited (or so I hope) second part of Big Idea 1: Spectroscopy. Let’s go over a few key points first!

• Spectroscopy is the study of matter using light.
• Light is Energy. Light is not just visible, but the entire Electromagnetic Spectrum: you know – radio waves, microwaves etc.
• Light is made of particles called photons. And it is these photons that carry energy. In fact, each photon carries energy = hn. Your main equations here are:

$E=h\nu$

$c=\nu&space;\lambda$

• There are many types of spectra (the result of spectroscopy): mass spectra, photo electron spectra, emission spectra, absorption spectra etc. And they are really easy to understand!

Keep watching for a brief overview of spectroscopy!

## Still Pulling Your Hair Out Over Chemistry?

Chemistry is often the hardest test in AP.

But it doesn’t have to be.

Not if you’re prepared.

It takes a bit more than just late nights and hard work.
