SUMMARY
The discussion centers on the relationship between power and intensity using the decibel scale, specifically analyzing a firecracker that emits 1200 W of peak power. Intensity (I) is defined as power per unit area, with the area in question being the surface area of a sphere. The formula I = P/A is confirmed, where A represents the surface area of the sphere, clarifying the calculation of intensity in this context.
