AS Level Physics - 7.3 The Doppler effect for sound waves

**This Powerpoint specifically uses the Cambridge AS Level international Syllabus (9702) and covers all criteria for – Unit 7.3 The Doppler effect for sound waves
**

Students will be able to

1 understand that when a source of sound waves moves relative to a stationary observer, the observed frequency is different from the source frequency (understanding of the Doppler effect for a stationary source and a moving observer is not required)

2 use the expression fο = f sv/(v ± vs) for the observed frequency when a source of sound waves moves relative to a stationary observer

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
