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 x 10¹¹V/m for a time of 1. ns. (a) (1 point) What is the maximum magnetic field strength in the wave? (b) (1 point) What is the intensity of the beam? (c) (1 point) What energy does it deliver on a 1mm² area?
