    Two coherent sources of intensity ratio a interfere In interference pattern, \[\frac{I{{\,}_{\max }}-{{I}_{\min }}}{{{I}_{\max }}+{{I}_{\min }}}\] is equal to:                     

    A) \[\frac{2\alpha }{1+\alpha }\]                

    B) \[\frac{2\sqrt{\alpha }}{1+\alpha }\]

    C) \[\frac{2\alpha }{1+\sqrt{\alpha }}\]                   

    D) \[\frac{1+\alpha }{2\alpha }\]

    Correct Answer: C

    Solution :

    [c] Ideal gas equation \[PV=nRT\] \[PV\propto T\] Area under PV graph \[\propto T\] Hence \[{{T}_{2}}>T{{}_{1}}\]
