Model a cancer cell as a circular disk 5.0 um in diameter, and let the light pulse last for 4.0 ns with a power of 2.0 × 10¹2 W. Assume that the energy is spread uniformly over the face of one cancer cell for each pulse. a. How much energy is given to the cell during this pulse? Show your calculation. b. What is the intensity (in W/m²) delivered to the cell? Show your calculation. c. What are the maximum values of the electric and magnetic fields in the pulse? Show your calculation, and don't forget units!
