It's called "vector addition," not "interaction."

A bit more on the lack of "interaction" between two waves...

A bit more on the "interaction" between two waves...

From "Optics", by Hecht: "Briefly then, optical interference
corresponds to the *interaction* of two or more light waves
yielding a resultant irradiance that deviates from the sum
of the component irradiances." (emphasis mine)

Since the "interaction" between two waves is good enough for
Hecht, it is good enough for me.
