Why does light refact when it passes from air into a glass slab?
Light bends when it passes from air into a glass slab due to the change in speed of light as it travels through different mediums. This change in speed causes the light to refract, or change direction, at the boundary between the air and the glass slab due to the difference in optical density between the two mediums.
In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
What will happen when ray of light passes through a glass slab?
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.
Why dispersion do not take place through glass slab?
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.
Why doesn't a clear window refract white light?
It does. The light refracts when it enters one side of the glass, and then it refracts in the other direction when it leaves the other side and goes back into air. The slab of glass doesn't distort the image, because its surfaces are flat and parallel. So light leaves the glass in very nearly the same direction as it was headed when it arrived.

What is the focal length of a rectangular glass slab?
The focal length of a rectangular glass slab is not applicable as it does not have the ability to converge or diverge light to form an image. The primary function of a glass slab is to refract light without focusing it at a specific point.

What happens when light is perpendicular to 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.
Why air bubble in a glass slab have silvery look?
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.
How do you determine refractive index of a glass slab?
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.
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.
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.
Can a glass slab bend different coloured lights by different amounts?
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.
