1they wont have a constant phase difference.
Two identical but independent monochromatic sources of light cannot be coherent.Why?

1well... its hard to maintain a constant phs diff between two 'independent' sources... although they will have same frequency (identical monochromatic source.)
1Y ????
thoeretically sab kuchh possible hai....
bus manlo,,, dono same phs diff banara! kam khatam...
1I think the mechanism of emission of light I dunno this by a source gives the answer . theoretically possible I think , but I dunno
Why don't the admins answer such Q's ?????[7]
24I may be wrong with explaination:::
Coherent sources are created in laboratory using slits which divide the wavefront of a particular source.
Wavefront is a characteristic property of source.So even if 99.99% identical sources are created we cant get identical wavefronts....there ought to be some phase diff due to which the 2 sources become incoherent........

12 indentical sources ahvin same wavelnght same amplitude may nt b cohernt cuz tehre may b sum chnages in d emision of light thus taht wud b diffrnt for both d sources so they r nt cohenrt n d inetrfrcnes pattrn is nt shrp n steady
