The light beam from a search light may have an electric-field magnitude of 1000 V/m, corresponding to a potential difference of 1500 V between the head and feet of a 1.5-m-tall person on whom the light shines. Does this cause the person to feel a strong electric shock? Why or why not?
Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time. These devices are called pulsed lasers and can be used to ignite nuclear fusion, for example. Consider a pulsed laser that produces an electromagnetic wave with a maximum electric field strength of 1.48×10^11 V/m for a duration of 1.00 ns. What energy does it deliver on a 1.00 mm^2 area? Give your answer in units of kilojoules.
