Default Constructive interference in radiowave propagation

They can and certainly do when no energy is passing through the
reflecting surface. In such a case the only energy conveyed by the
wave is that which is reflected. The 100% number comes not in a
single bounce, or from a single wavefront. But I don't expect you to
understand this.

The waves existed along with their energy components before
they were canceled.


I believe your misunderstanding probably lies somewhere within that
statement. It does not convey concise meaning.

What happens to those energy components
after the waves are canceled.


Where there are waves, there is energy. Where there are no waves,
there is no energy. Show me the canceled waves.
