| From reviewer 2: The electric field vectors are drawn very big and there are relatively few of them. The diagrams look somewhat coarse. Since these are movies and the vectors do not have to be generated in real time by the computer, vector diagrams with somewhat higher resolution seem appropriate.
The charged disk clip illustrates edge effects correctly but does not convey that the field near the center of the disk are nearly constant as a function of distance. Also, in one of the movies just 3 rows of vectors are drawn, instead of extending the vector diagram over the whole viewing window.
This reviewer also had concerns that the clip showing a 2D view of an accelerated charge might oversimplify subtleties in ways that could be
misleading. The text accompanying the movie states "At the boundary between these two regions the field is transverse (shown in red)",
and the graphics seem to convey the same message. The radiation field is transverse, but the static and induction fields are not. At small distances these fields will be much larger in magnitude than the radiation field.
It is not advisable to try to make field lines represent the static field and the radiation field at the same time. |
