If an absolute intensity at 4.00 m is 6.00x10-8W/m?, what is the absolute intensity at the following distances? a. 8.00 m b. 12.0 m c. 20.0 m d. 2.00 m 4. What are the relative intensities at each of the above distances? a. 8.0 m b. 12.0 m c. 20.0 m d. 2.0 m 5. An intensity of 1.28 x 10-1 W/m is measured at 5.25 m, what is the absolute intensity at 6.33 m? What are the relative intensities at both of these distances
