The tables for you guys to paste the data into

AN -antinodal lines- constructive interference- also called maxima

N -nodal lines- destructive interference- also called minima

Use the "Measuring Tape" to measure 'd'

Treat the right-most side of the simulation the 'screen'. Measure 'L'

Part A: Using

Getting Started The simulator Fhet Interference Simulator shows an interference pattern between waves created by point sources that are vibrating in phase. Ensure that you choose 'lnterference' and Light options. See image below for setup. The tape measure icon in the top right allows one to measure distances.

The paths from each source to a point P are shown below as are the lengths of these paths. measured in centimetres. PS1 is the path length from source 1 to the point and P82 is the path length from source 2 to the point. \fNote that the central antinodal line (AND): is given the number m = 0. As you move away from this central antinodal line, the antinodal lines are given numbers, 1, 2, 3, etc., regardless of which direction from the centre you move. Likewise, although it is not shown in the simulator's diagram, the nodal lines (N1, N2 etc) are also numbered n = 'l, 2, 3, etc. There is n = D nodal line. You may move the green point to any place on different nodal lines and antinodal lines. As you do so, the path lengths from the sources to the point will change, and the measurements will be indicated for each path.
