In a Young's double slit experiment the intensity of the resultant wave at a point P on the screen is l where the path difference between the waves from coherent sources \[{{S}_{1}}\] and \[{{S}_{2}}\] is \[\lambda \]. Then the intensity of the resultant wave at a point where the path difference is \[\lambda /4\] is given by
