Two point monochromatic and coherent sources of light of wavelength 
are placed on the dotted line in front of a large screen. The source emit waves in phase with each other. The distance between 
and 
is 
while their distance from the screen is much larger. Then –
A
If 
, O will be a minima
, O will be a minima B
If 
, there will be a total of 6 minima on screen
, there will be a total of 6 minima on screen C
If 
, there will be one maxima on the screen
, there will be one maxima on the screen D
If 
, there will be two maxima on the screen
, there will be two maxima on the screen
