Aspherically-spreading em wave comes from a 104.0 w source. at a distance of 9.6 m, what is the intensity of the wave?

Approximately 0.0898 W/m².

Explanation:

The intensity of light measures the power that the light delivers per unit area.

The source in this question delivers a constant power of . If the source here is a point source, that of power will be spread out evenly over a spherical surface that is centered at the point source. In this case, the radius of the surface will be 9.6 meters.

The surface area of a sphere of radius is equal to . For the imaginary 9.6-meter sphere here, the surface area will be:

.

That power is spread out evenly over this 9.6-meter sphere. The power delivered per unit area will be:

.
