The Doppler Effect [EN]

What Will You Learn?

• Understanding the Doppler Effect: They will observe firsthand how the frequency of a sound shifts when the source of the sound is moving relative to the observer. This demonstrates a fundamental concept in wave physics, helping them connect everyday experiences (like hearing a passing siren) with scientific principles.
• Practical Use of Technology: Working with a Doppler effect unit introduces students to modern tools and techniques in scientific research, fostering their technical literacy and interest in STEM fields.
• Application of Scientific Methods, Data Analysis and Critical Thinking: By using a microphone and Audacity, students learn how to record and analyze sound while gaining valuable experience in designing experiments, collecting data, and drawing conclusions based on their observations. Moreover, Audacity enables them to analyze frequency shifts in the sound recording, which helps develop their skills in comparing experimental results with theoretical expectations.
