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 1.51 x 1011 v/m for a time of 1.35 ns. (a) What is the maximum magnetic field strength (in T) in the wave? (b) What is the intensity (in W/m?) of the beam? W/m? (c) What energy (in k) does it deliver on a 1.52 mm area? kJ
