largeur a

teta radian CHANGER CALCULATRICE
teta=lambda/a
tan teta=opp/adj
=l/2D
lamda/a=l/2D
trou ; teta=1,22*lambda/a
onde lumneuse: a=<100 lambda
onde mécaniqye : besoin milieu 
materiel pour se propager

Interference: Deux onde mm 
frequence se superposent
interfange: distance qui separre
2 frange brillante consecutives 

calculer sigma/lambda:
  entier: Construcve, brllante
  sigma=S1M-S2M
  sigma=k*lambda

  pas entier:destrucive,sombre
  sigma=(k+1/2)*lambda
