plan and perform a first-hand investigation to gather data to identify the relationship between wave-length, frequency and pitch of a sound

Background

A Cathode Ray Oscilloscope (CRO) is a device which is used to display the nature of waves on a screen. You should have done an experiment using an oscilloscope .You can find instructions for setting up a CRO at Using an Oscilloscope (external website) Doctronics Educational. If you do not have access to a CRO download the oscilloscope from this webpage and enter sound through your computer microphone. Virtual oscilloscope (external website). Peter Debik.
