Ladder operators in angular momentum

💻 Book a 1:1 session: https://docs.google.com/forms/d/e/1FA...

📚 Ladder operators allow us to increase or decrease a component of angular momentum by a discrete amount hbar. These operators are extremely useful because angular momentum is indeed quantized. In this video, we derive a long list of properties of ladder operators that will prove extremely useful in our study of angular momentum.
