I know the answer would be yes, but why?
In class, I learned that energy is scalar and cannot be negative (at least in undergraduate class). Thus adding two sources of energy should result in a higher level of energy in general. But here for wave, if we have 2 waves that do destructive...
Sorry for asking this but what is E and H? And is the Power Flow you mentioned is a theory or such? I don't remember hearing those words before in class and not sure how to Google it
As I learn in class, when EM wave goes from medium 1 to medium 2, there are 3 possibilities that can happen
Totally transmitted (i.e when the angle of incident is 0 degree)
Partially transmitted and reflected (i.e when the angle of incident is between 0 and critical angle)
Total internal...
When I asked my professor "how do you find an answer for a question you don't know about Physics online" this is the site he recommended to me. Since most of my questions are about the theory more than the "homework" type, it's very hard to search for answers online.
