DESCRIPTION
파동광학 wave optics. 빛도 역학적 파동과 마찬가지로 간섭 현상을 나타낸다 . 보강 간섭 constructive interference. 상쇄 간섭 destructive interference. 회절. 빛의 간섭 현상을 관측하기 위한 조건. 광원에서 방출되는 빛들은 일정한 위상을 유지하여야 한다 . (coherence). 빛은 동일한 파장의 빛이어야 한다 . ( 단색광 ) . 레이저는 이 두 조건을 모두 만족시키는 광원이다 . - PowerPoint PPT PresentationTRANSCRIPT

"Newton's rings" interference fringes between 2 plano convex lenses, placed together with their plane surfaces in contact. The rings are created by interference between the light reflected off the two surfaces, caused by a slight gap between them, showing that these surfaces are not precisely plane but are slightly convex.
