In Young's double slit experiment a single source is used to illuminate two slits which then acts as two coherent sources to produce interference pattern. But, what if I put color filters on the two slits. Will it make the slits incoherent?
I myself think yes because in one of my previous questions here I got to know that two different sources cannot be coherent. Put filters will make the slits act like two different sources which are not coherent as light is coming through two different filters.
Is my thinking correct?
