Longitudinal waves can also be simulated in Excel. This time the points are being displaced horizontally we will start with 3 points. Set up the spreadsheet as shown below. The slider is set to vary cell G5 from 0 to 30,000 in steps of 1. To make the time (F5) change in smaller steps it is calculated from G5/1000.The displacement is the original position – Asin(2πft)Insert an xy scatter based on columns B and C and...
