Hi all. Just wondering. Any difference - from the viewpoint of a swimmer - when one swims in water waves of short wavelength as compared to large wavelength? I read about this somewhere before in a newspaper article. The difference will be apparent when the length of the swimmer's body is comparable to that of the wavelength. (Why?) (disclaimer: I understand that the higher the frequency of waves, the more energy it contains. But still i don't see how it affects to the ease of swimming in them.) Can forummers shed light on this issue. I am a high school physics teacher. Someone once remarked that once i state down my job title (ie a teacher), people will be more forthcoming with their replies.
