Question
![Exercise -2-
Light interference is achieved with the help of young's slits. The F₁ and F₂ slits are distant of
a = 0.20 mm and the interference is observed on a screen located at the distance of D = 1.0 m of these
slits.
The light source F is monochromatic wavelength = 0.64 µm and acts as a synchronous source and in
phase. It is located at equal distance from F1 and F2.
M, a point of the interference figure is observed on the screen, M is located at distance d₁ of F₁ and d₂ of
F2.
1- Are the luminous waves from F1 and F2 coherent?
2-
Under what conditions will the point M be a shiny
(bright) fringe? a dark fringe?
3- What can be said of the following points M if:
M is such that d₂-d₁ = 0
M is such that d₂-d₁ = 3.2 μm
M is such that d₂-d₁ = 2.24 μm
