IB Physics Exam Preparation - Atomic Physics - Energy levels

This video is aimed at IB (SL or HL) or A-Level students preparing for their exams .

In this episode, we will be working on an exercise inspired by past papers that deal with calculations in regards to atomic energy levels and emission spectra.

An exercise will appear on the screen. Pause the video and work it out by yourself. Then, we will review the exercise together.

The text of the exercise can be consulted here: Page 1 (questions a & b): https://s26.postimg.org/5ky5f77nt/Page1_C.jpg

This video is the fifth episode of the Atomic Physics Series. It is a direct application of the knowledge compiled in the first 4 episodes:

View the 4 first episodes if you haven't done so yet:

Episode 1: "Energies in an atom". This episode introduces the series by reminding the viewer of the concepts of energy (Kinetic, potential, internal and mechanical). Within this context, it discusses the energies involved in an atom of Hydrogen. https://youtu.be/g9ieCabz_PI

Episode 2: "What is light", that describes how an atom can gain or lose energy. https://youtu.be/XwNsi1vzjTs

Episode 3: "Energy levels of an atom", that explains that the energy of an atom can only take specific values. This shows why atoms can be characterized by their emission or absorbtion spectra. https://youtu.be/MHJO6pm-hoM

Episode 4 (IB Physics High Level): "Deriving Energy Levels of the Hydrogen Atom". It presents how to derive the energy levels of a Hydrogen atom from scratch in 6 easy steps! It is a beautiful demonstration that reminds us that art and science are really not that far apart (this derivation is to be known for the exam). https://youtu.be/YW_g3dy0HOg
