A) \[\left( n+\frac{1}{2} \right)\lambda \]
B) \[n\lambda \]
C) \[\left( n-\frac{1}{2} \right)\lambda \]
D) \[\frac{\lambda }{2}\]
Correct Answer: B
Solution :
The path difference \[{{S}_{1}}P-{{S}_{2}}P\] is a whole number of wavelength, the fringe at P is dark no bright. So, \[{{S}_{1}}P-{{S}_{2}}P=n\lambda \](for minimum intensity)You need to login to perform this action.
