Concept

Problem: 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 ' tabindex="0">1.00×1011 V/m for a time of 1.00 ns.(a) What is the maximum magnetic field strength in the wave?(b) What is the intensity of the beam?(c) What energy does it deliver on a ' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm

Problem Details

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 ' tabindex="0">1.00×1011 V/m for a time of 1.00 ns.

(a) What is the maximum magnetic field strength in the wave?

(b) What is the intensity of the beam?

(c) What energy does it deliver on a ' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm' tabindex="0">1.00-mm
