What does electromagnetic wave literally look like? Some people on the Internet called electromagnetic wave as something that has literally only two dimensions, I think it is because of this over-publicized picture http://hyperphysics.phy-astr.gsu.edu/hbase/emwav.html. Is it true? Personally, I don't think electromagnetic wave is two-dimensional despite most pictures depicted it as a two-dimensional wave. What do you think?
