Question

(8%) Problem 11: Lasers can be constructed to produce an extremely high-intensity electromagnetic wave for a very brief time Such lasers are 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 0.18 x 101 V /m for a time of 0.75 ns Randomized Variables Eo 0.18 x 1011 V/m t= 0.75 ns 33% Part (a) What is the maximum magnetic field strength in the wave Bo, in teslas?
