In IB Physics First Assessment 2016, single-slit diffraction is a subtopic of Topic 9, wave phenomena. This subtopic has only the following understanding: “The nature of single-slit diffraction.”

Frequency distribution of questions by single-slit diffraction understandings for HL

Between 1999-2023

For the entire dataset for HL, all of the questions came from the nature of single-slit diffraction.

Figure 1

Between 2016-2023

Between these years, the distribution is the same. All questions came from that understanding because there was only a single understanding.
