20 pts Question 4 Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time- called pulsed lasers. They are used to ignite nuclear fusion, for example. Such a laser may produce an electromagnetic wave with a maximum electric field strength of 1.46x1011 V/m for a time of 0.97 ns. What is the energy in kJ delivered on a 1.09 mm2 area?
