Physics term describing waves or light that maintain a fixed phase relationship, enabling interference. Used in technical contexts.
Laser light is a coherent light source.
Coherent waves produce interference fringes.
干渉 is the noun 'interference'; 可干渉的 is the adjectival noun meaning 'coherent' (capable of interference).
The loanword コヒーレント is more common in modern physics texts, while 可干渉的 is a kanji-based equivalent used in some Japanese academic writing.
incoherent
Compound of 可 (possible), 干渉 (interference), and the adjectival suffix 的, literally 'interference-possible'. A technical term coined in Japanese for physics.
