triangle ABC
angle BAC=alpha
angle ABC= beta 
angle BCA = gamma
BC/sin alpha = CA/sin beta = AB/sin gamma
interfrange angulaire ia=lambda/distance separant 2 fentes

 on veut la position du pt I ou a lieur la refraction issue de la source S et parvenat en P. loi de moindre temps => on doot trouver z et y tq tau= n1 SI/C+ n2 IP/C minimal. => L=n1 SI + n2 IP minimal.
 z=0, tous les rauons sont coplanaires
 l(y)=n1sqr(d^2+y^2)+n2sqr(D^2+(b-y)^2)
 lim L(y) en +- l'inf = +inf donc L presente au moins un min qui annule la derivée. On a L'=0 et on résout
 
 puit harmonique=V(x)=1/2 m wo^2x^2
=> oscillateur quantique Emin=hbarrewO/2
