the medium which have the same refractive index as glass.
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
It is because the central portion of the lens i.e. optical centre can be considered similar to a parallel sided glass slab.
When light passes into the slab it is changing medium from less to more dense. When that happens the light slows down and bends towards from the normal
Because glass slab is optically denser than air.

, this is ojashwin mishra---- lateral displacement increases with the increase in thickness of the medium. it doesnt have any relation with the width of the glass slab

When we keep the glass slab over some printed matter, the light coming from the letters (after reflection ) face change of medium at glass-air interface. Since glass has more refractive index than air, the light bends away from the normal as it goes out of glass. This apparently causes us to see the letters raised. Hope this clarified your doubt.

GIC has silicate 'GLASS' in it's powder and so while mixing on glass slab the polyacrylic acid attack the glass content of glass slab. This may even alter properties of GIC.
The refractive index of prism is very high but its very low in glass slab, in glass slab the dispersion occurs but its very less, so is not visible.
Because glass slab is optically denser than air.
refractive index of glass is higher than refractive index of glass slab OR density of air is less than density of glass

To find the refractive index of a glass slab using a travelling microscope, you would first place the glass slab on a flat surface. Using the travelling microscope, measure the apparent shift in the position of the object when viewed through the glass slab. By knowing the thickness of the glass slab and the shift in the position, you can calculate the refractive index using the formula: Refractive index (n) = (apparent shift + 1) / actual shift.
