%X We discuss the electric fields and light energy reflected by anti-reflective coating and the interference of the electricfields. By emphasizing that the light energy is determined by the total, rather than individual, electric field, we clarifythe confusion about how the anti-reflective coating increases the transmission energy. An example shows that themain electric fields of destructive interference on a coated surface are from the first and second reflections
