Ahuman wave. during sporting events within large, densely packed stadiums, spectators will send a wave (or pulse) around the stadium (fig. 16-29). as the wave reaches a group of spectators, they stand with a cheer and then sit. at any instant, the width w of the wave is the distance from the leading edge (people are just about to stand) to the trailing edge (people have just sat down). suppose a human wave travels a distance of 853 seats around a stadium in 39 s, with spectators requiring about 1.8 s to respond to the wave’s passage by standing and then sitting. what are (a) the wave speed v (in seats per second) and (b) width w (in number of seats)?
