Question 29
A sound engineer measured a sound using an oscilloscope. He obtained a waveform of height 4 cm and a complete cycle time of 4 ms (milliseconds).
Work on your own to draw a waveform graph of the sound wave, showing three cycles.
You will need graph paper, a ruler, a pencil and a flexible ruler (Figure 11.27).
Share your graphs in class.
