Want this question answered?
Actually a glass slab is made up of two triangular prisms placed inverted to one another. So dispersion taking place by the first prism is counter acted by the inverted prism and hence no dispersion is seen on a whole
surface tension
A prism breaks up white light into the light spectrum that shows each different color. However, a rectangle does not have the edges needed to break the light up.
give reasons: 1) lemons kept in a glass of water appear enlarge. 2)dispersion cannot take place through a glass slab. 3)fuse wires or miniature circuit beakers are not used in a circuit containing electriccells why? 4)a stationary charge cannot produce electric field.
speed of light will decreases

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.
The light strikes on one surface of the prism undergoes refraction and passes through the glass of the prism, and when emerges out, it refracts again. This causes the dispersion of the light and splits the light into its constituent colours. The degree of bending depends on the angle at which the ray of light enters and leaves the faces of the prism. The faces of the prism are not parallel to each other. For a glass slab, the opposite faces of the slab are parallel. So only a slight deviation occurs.

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.
White light is actually a combination of all of the colors of all of the rainbow. It splits in a prism because the prism can pick up the differences. However, it will not in a glass slab because the slab is smooth and will not reflect all of the different colors of light.

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.
it becomes kinda prism
Because glass slab is optically denser than air.
