(b) show that the average energy density of the electric field equals the average energy density of the magnetic field in an em wav

Answer 1

appears that a carnival of sorts has rolled into town. The author describes the affair as ''all sorts of fun and gambling and side-shows,'' brought to town by ''a showman owning an institution called the Gaiety Land.'' Gaiety means happiness or excitement.
