Young's experimental setup can be used to monitor the width of the lead wires in transistors. The cables are placed in a narrow opening as shown in the figure. The opening is illuminated with highly coherent light. The position of the tenth maximum is measured on a screen located at 0.5m. The expected diameter of the wires is 0.100±0.005 mm.
