## What do you learn in Molecular Physics

Molecular Physics digs into the behavior of atoms and molecules, exploring their structure, interactions, and properties. You'll study quantum mechanics, spectroscopy, and molecular dynamics. The course covers topics like chemical bonding, molecular symmetry, and how molecules respond to electromagnetic fields. It's all about understanding matter at the molecular level and how it influences larger-scale phenomena.

## Is Molecular Physics hard?

Molecular Physics can be pretty challenging, not gonna lie. It combines concepts from physics, chemistry, and math, which can be a lot to juggle. The quantum mechanics part often trips people up, and the math can get intense. But don't freak out - if you've got a solid foundation in basic physics and chem, you'll manage. It's tough, but also super interesting once you get into it.
