3Aragorn we cant make a sodium vapor lamp contain sodium to emit all the frequencies of light.

1@priyam.... it can be of course.......but there may be slight variation in wavelenth.........(negligible)

11Conclusions: Moms know everything and Virgin Mobile is the best!
1@priyam.....ask ur dad r mom to get that too.......(virgin mobile)..
take dat to iit entrance n keep on thinkin lik dat....
33Hatke hi soch rahe hai ...
think of economic crisis so why waste money on two sources...
relate this question to economic crisis thats called think hatke ...
(so i should think hatke widout virgin mobile :P)
1@priyam..mom knos everythin...............he he he.....;-)
3it is a probability that an atom can absorb energy and then the electrons excite to get the light energy
33messsage@Ram.com
they will be slight (many ) differences at molecular level in the twins too... how do their mother recognise them.... mamta differenciates naa so there must be some difference:P
:P
33If U can do it by same source in many ways why waste money on two sources :P
11Arey, yaar. I'm asking when you can manipulate almost everything in the world, why not manipulate this?
3two sources cant be made coherent because the emission of lightby the atos of one source is independent of the other.
11Anyway, we can make the phase diff bet the two light waves to be a constant, right?
1it depends also on wavelen of d sources u take... they shld be of same range...so accordingly decide.........
11Can't we modify the sources so that the phase difference is constant?
1sky is rit....
@ sparkle...(fr last post) by two sources identical wat do u mean??
1It means it is not a necessity right? what if i use identical but independent sources?
