In IB Physics First Assessment 2016, the Doppler effect is a subtopic of Topic 9, wave phenomena. This subtopic has only the following understanding: “The Doppler effect for sound and light waves.”

Frequency distribution of questions by Doppler effect for HL

Between 1999-2023

For the entire dataset for HL, because there is a single understanding, all questions came from the Doppler effect for sound waves and light waves.
