A) At O
B) Above O
C) Below O
D) Anywhere depending on angle\[\theta \], thickness of plate t, and refractive index of glass\[\mu \]
Correct Answer: D
Solution :
[d] If \[d\sin \theta =(\mu -1)t,\] central fringe is obtained at O. If \[d\sin \theta >(\mu -1)t,\]central fringe is obtained above O. If \[d\sin \theta <(\mu -1)t,\]central fringe is obtained below O.
