we have not kept 2 glass slabs
i am telling that same happens when u keep 2 glass prims

no it won't coz their are 2 prisms but in case of slab its only one how it can refract and becomes again white light
bcoz glass slab has 2 parallel sides
on refracts white light into 7 colurs and tgen tge other makes all the colours white again
