LEsson 1

In this lesson, we will learn about the experiment that destroyed one model in physics and created a new one. We will also look at quantization of light via absorption and emission and the beginnings of the Bohr model of the atom.

Topic E.1 - Lesson 1 - Bohr Model

LEsson 2 - AHL

In this lesson, we will look at quantization of angular momentum, the closest distance that an alpha particle can come to a nucleus, nuclear density, and briefly touch on electron diffraction.

TOK linKs

How did the results of the Rutherford-Geiger-Marsden experiment, which contradicted the existing "plum pudding" model of the atom, catalyze a paradigm shift in atomic theory?

What does this reveal about the relationship between empirical data and the evolution of scientific understanding?
