Spectrum is dispersal of light in all composition of color ex whit light disperse in all 7 color..
Spectrum is occurred in prism but not in glass slab due to the glass slab is formed by combination of two prism.. so,in glass slab twice refraction take place..1 time it dispersal in all its color but in 2 time all color combinations once again by this Spectrum are not occur in glass slab..

We know that in the case of a rectangular glass slab, where to setting surfaces of the glass slab are parallel to each other, the emergent ray is parallel to the incident ray. That's why spectrum is not formed when the light rays are passed through the it.
