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
When a ray of light passes through a glass slab, it will undergo refraction. The light ray will bend towards the normal as it enters the glass slab, and then bend away from the normal as it exits the slab. The path of the light ray will be slightly shifted from its original direction.
Light refracts when it passes from air into a glass slab due to the change in speed of light as it moves from one medium to another. This change in speed causes the light rays to bend, following Snell's Law, which states that the angle of refraction is determined by the ratio of the speeds of light in the two different mediums.
Dispersion does not occur in a glass slab because the different colors of light all travel at the same speed in the glass medium. Since dispersion is the phenomenon where different colors of light travel at different speeds, it does not occur when light passes through a homogeneous medium like a glass slab.
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.
The refractive index of a glass slab can be determined by measuring the angle of incidence and the angle of refraction as light passes through the slab. By using Snell's Law (n1sin(θ1) = n2sin(θ2)), where n1 is the refractive index of the medium before the glass slab, θ1 is the angle of incidence, n2 is the refractive index of the glass slab, and θ2 is the angle of refraction, the refractive index of the glass slab can be calculated.

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.

the medium which have the same refractive index as glass.
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.
Yes, a glass slab can bend different colored lights by different amounts due to the phenomenon of dispersion, where light of different colors is refracted by different angles, resulting in a separation of colors. This is why we see rainbows when light passes through raindrops or a prism.
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 wavelength of light decreases as it enters a glass slab from air. This is because the speed of light is slower in glass than in air, causing the frequency of the light to remain constant while its wavelength decreases.
