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.
The cross-sectional area of a concrete slab is the total area of the slab when viewed perpendicular to its length and width. To calculate the cross-sectional area, you multiply the length of the slab by the width of the slab. This measurement is crucial for determining the amount of concrete needed for a project and for ensuring the structural integrity of the slab.
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
Probably none because a slab of granite would be measured in cubic feet.
Usually the serif fonts are divided into 2 categories, slab serif and serif. Clarendon is an example of a slab serif.
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
In a rectangular glass slab, the emergent ray is parallel to the incident ray because of the principle of refraction. When light enters a denser medium (like glass) from a rarer medium (like air), it bends towards the normal. As the light exits the glass slab and reenters air, it bends away from the normal. The combination of these two refractions results in the emergent ray being parallel to the incident ray.
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.
When a light ray enters a rectangular glass slab at an angle, it bends towards the normal due to refraction. As it exits the glass slab, it bends away from the normal by the same amount due to refraction again. The angles at which the light ray enters and exits the slab are such that they cancel out the overall deviation, resulting in the emergent ray being parallel to the incident ray.

No, the incident ray and emergent ray will not be parallel if the glass slabs have different refractive indices. This is because the light rays will experience refraction at each interface as they pass through the slabs due to the change in refractive index, causing the emergent ray to be offset from the incident ray.
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.
The lateral displacement (D) of an incident ray passing through a glass slab can be calculated using the formula D = t * sin(i - r), where t is the thickness of the glass slab, i is the angle of incidence, and r is the angle of refraction. This formula takes into account the deviation of the ray as it passes through the glass slab.
The ray of light should be incident perpendicular to the surface of the glass slab. This ensures that the light ray does not get deviated or displaced while passing through the glass slab, emerging on the other side in the same direction.
it becomes kinda prism
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
When light is perpendicular to a glass slab, it passes through unaffected without any deviation in its path. This phenomenon is known as normal incidence, where the incident light ray and the refracted ray are along the same line.
