Hello,

Along the lines of Electromagnetic Radiation, such as a visible light wave:

First, am I correct in thinking that two such waves 100% destructively interfered still propagate (if both wave going in same direction)?

If so, is there a way to "de-interfere" (for lack of better known term) the waves so that, in the case of light waves, they would become visible at a receiving point?

Sorry if too may questions in one post but this is interrelated:

Can such completely destructively interfered EM waves be detected, in that state?

Thanks in advance for any insights.
