Step 1
State the intensity when the distance from the source is 2 m.
Answer
To find the intensity when the distance from the source is 2 m, we refer to the provided graph. At 2 m on the x-axis, we draw a vertical line up to the curve and then move horizontally to the left to read the corresponding intensity value on the y-axis. The graph indicates that the intensity at this distance is approximately 55 W/m².
