When one slit is covered with red filter and the other with a blue filter, the phase difference at any point on the screen will continuously change producing uniform illumination, Reason (R): Two independent sources of light would no longer act as coherent sources.

    A)                                 both A and R are true and R is the correct  explanation of A

    B)                                 both A and R ane true but R is not the correct  explanation of A
