解释
Identical (I): The waves should have the same frequency and wavelength.
Coherent (III): The waves must maintain a constant phase relationship.
Monochromatic (IV): The waves should have the same frequency (which is closely related to being coherent).

Monochromatic (IV): The waves should have the same frequency (which is closely related to being coherent).
