This is because the amount of refraction taking place at the parallel faces of a glass slab is equal but opposite and since the faces are parallel the emergent ray emerges parallel to the incident ray with lateral displacement.

Cross sectional area of concrete slab?
The cross sectional area of a slab can be found by squaring the height of the slab.
How do you calculate the volume of concrete in a circular slab?
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
How do you calculate the area of a rectangular slab?
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
How many square feet in a slab of granite?
Probably none because a slab of granite would be measured in cubic feet.
What are the types of serifs?
Usually the serif fonts are divided into 2 categories, slab serif and serif. Clarendon is an example of a slab serif.
The incident ray and the emergent ray will always be?
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
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.
What is a glass slab?
it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.

How can the lateral displacement of the emergent ray with respect to incident ray in glass slab be increased?
Lateral displacement increases if the: 1. Angle of incidence is increased. 2. Refractive index is increased 3. Thickness of the medium( i.e. here in your case the glass block) is increased.
What is the angle between incident ray of light and emergent ray of light when incident ray of light falls obliquely?
The angle between the incident ray and emergent ray is called the angle of - DeviationIt depends on the refractive index of the glass slab, the material the light is traveling through before hitting the slab as well as the angle it hits the slab at.Snell's law:The refractive index of the medium the light is traveling out of - times - sin for the angle between the ray of light and the normal of the surface = the refractive index of the medium the light is traveling into - times - sin for the angle between the ray of light and the normal of the surface on the other side.n1 * sin(angle1) = n2 * sin(angle2)Where:n1 = Refractive index of the material the light is exiting.sin(angle1) = Sin for the angle at which the light hits the surface of the glass slab. This angle is measured by drawing a line from the point on the glass slab that the light hits the surface perpendicular to the surface, that is to say at a 90 degree angle against the surface. You then measure the angle between this new line and the line of the ray of light.n2 = Refractive index of the material the light is enteringsin(angle2) = Sin for the angle at which the light leaves the edge of the glass slab.Illustration:http://www.math.ubc.ca/~cass/courses/m309-01a/chu/Fundamentals/snell01.gif
What happens if light is passed through a glass slab whose sides are not parallel?
it becomes kinda prism
How should a ray of light be incident on a glass slab so that it comes out from the opposite side of slab without being displaced?
The question is phrased very poorly, as the photon is by definition displaced after traveling through the slab. If you meant "deflected", however, it must be normal.
What is the formula for finding the lateral displacement of an incident ray when it passes through a glass slab?
S = t*sin( theta1 -theta2)/cos(theta2)
Why does dispersion take place in only a prism and not in a glass slab?
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.
Why glass ionomer cement not mixed on glass slab?
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.
Why does not a glass slab disperse light?
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.
