# Preamble

# Learning objectives

By the end of this chapter, you should be familiar with the concept of quantum mechanics and light, the history of the various atomic models proposed and the reasons propelling them. You will also be introduced to the field of spectroscopy as means to study light and atoms together. Finally, a mention about the modern interpretation of quantum mechanics with wavefunctions and probabilities is made.

# Learning flow

This chapter will span 2 weeks.

Before week 3 lecture, do the pre-lecture homework and briefly read through sections 3.2, 3.3, and 3.4.

During week 3 lecture, we will discuss the topics of light, spectroscopy and early atomic models in 3.2, 3.3, and 3.4. The content is heavy and possibly dry. Hence we intend to deliver the content via the associated lecture activities, which are more hands-on and visual. That is the plan, at least.

Before week 4 lecture, no pre-lecture homework. Just briefly read through sections 3.4 and 3.6 .

During week 4 lecture we will go explore some aspects of modern quantum mechanics.

In week 4 IS, we will do discussion questions 1-6.

In week 5 IS, we will fully understand the quantum mechanics of a particle in a box through questions 7 and 8.
