Multiple electromagnetic fields can fill the same space simultaneously as long as they have a different vibrating frequency. An example of this is the fields present in sunlight, which can be separated with the help of a prism. This is different from material objects which cannot simultaneously fill the same space (except perhaps in some cases).
A couple of questions about this:
- what is the minimum difference that must exist in the vibrating frequencies in order for the fields to not conflict with each other?
- why does the vibration frequency make a difference? What I mean is, what aspect in the structure of the Universe causes two fields with different frequencies to be able to co-exist in the same space?
Thanks in advance,
