Question

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 2.5 x 1011 V/m for a time of 1.00 ns. What is the maximum magnetic field strength in the wave?

Answer 1

The maximum magnetic field strength is 833.33 T

Step-by-step explanation:

The maximum magnetic field strength is equal:

`B=(E)/(c)`

Where

E = electric field strength = 2.5x10¹¹V/m

c = speed of the light = 3x10⁸m/s

Replacing:

`B=(2.5x10^(11) )/(3x10^(8) ) =833.33T`
