Forensics Case 3 - Name That Tune: Matching musical tones through waveform analysis

Activity Overview

In this activity, students analyze sound waves to calculate the frequency or pitch of musical notes. They use a Microphone to detect the waveform of a musical note. Students calculate the frequency of a musical note from the period of its waveform and use this knowledge to identify the musical notes that make up the combination to a safe.
