What else can I help you with?
In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
Is incident ray parallel to the emergent ray through two glass slab of different refractive index?
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.
Why glass slab does not produce dispersion?
Glass slabs do not produce dispersion because dispersion requires different materials with varying refractive indexes to separate light into its different spectral components. Glass slabs are made of the same material throughout and do not have the necessary variation in refractive index to cause dispersion.
Why does glass slab not cause dipersion?
Glass slabs do cause dispersion of light, but it may not be as prominent as in other materials due to their relatively low refractive index compared to materials like prisms. Dispersion is the phenomenon where different colors of light are spread out due to their different wavelengths. In glass, the dispersion effect can be seen at the edges of the slab or in certain conditions where the light path is longer.
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
Refractive index of a glass slab using a travelling microscope?
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.
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.
In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
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.
Is incident ray parallel to the emergent ray through two glass slab of different refractive index?
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.

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.
How do you xxplain the cause of dispersion?
When composite white light with seven colours as constituents enter into triangular prism, then different colours get refracted at different angles because of the different refractive index value of glass for different colours. Refractive index is defined as the ratio of the speed of light in free space to that in the glass medium. As the speed of the different colour differ, the refractive index varies. Hence they have different angle of refraction. So all the colours have been split up. As we use a triangular prism, as the refracted colours fall on the other face of the prism, once again separation becomes possible. Hence the phenomenon of dispersion. But this will not be possible when we use a rectangular glass slab. So triangular prism is essential to have dispersion.
When a thick glass slab is placed over some printed matter the letters appear raised when viewed through the glass slab. Why?
When we keep the glass slab over some printed matter, the light coming from the letters (after reflection ) face change of medium at glass-air interface. Since glass has more refractive index than air, the light bends away from the normal as it goes out of glass. This apparently causes us to see the letters raised. Hope this clarified your doubt.
Why does a ray of light passing through a glass slab not show dispersion?
Actually a glass slab is made up of two triangular prisms placed inverted to one another. So dispersion taking place by the first prism is counter acted by the inverted prism and hence no dispersion is seen on a whole
