Infinity, as rays after refraction neither actually nor appears to meet.
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.
When light passes from one medium to another with different densities, such as air to glass, some light is reflected at the interface. This reflection of light creates a silvery appearance on the surface of the air bubble in the glass slab. The color is a result of interference between the reflected light waves.
A slab caster is a machinery used in the steel industry to continuously cast rectangular slabs of steel from molten metal. It involves pouring molten metal into a tundish, which then flows into a water-cooled copper mold to solidify and form the slab shape. The slabs are then further processed into various steel products.
This is pretty easy to answer.The fact is that no matter how smooth a surface appears to the naked eye, at the microscopic level there are bound to be imperfections. Think of a glassy smooth marble - it rolls effortlessly (almost!) and feels smooth but if you look at it under a microscope, you will see many imperfections, jagged edges and cracks.Similarly, a glass slab has these imperfections. Over a large area of the slab, these will cause a large frictional force that becomes obvious when you try sliding them against one another.

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.
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
It is length*width*height - in suitable measurement units.
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.
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.
when the length of the slab is more or equal to twice the breadth hence it has to be one way slab.
Dispersion of light occurs due to different colors of light having different speeds in a medium. When light passes through a rectangular glass slab, the different colors of light follow the same path, experiencing the same amount of refraction. This results in no dispersion of light as all colors exit the slab without separating.
the medium which have the same refractive index as glass.
Glass ionomer cement should not be mixed on a glass slab because the ions present in the cement can react with the glass slab, leading to contamination and affecting the setting reaction of the cement. This can compromise the physical properties and performance of the cement. It is recommended to use a disposable mixing pad or a mixing paper to prevent any unwanted reactions and ensure the proper setting of the glass ionomer cement.
Depending on the type of glass your glass slab is made of, it will have a different refractive index. Common microscope slides are made of soda-lime glass, which have a refractive index of 1.46.
