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
Why there is no dispersion of light refracted through a rectangular glass slab?
A prism breaks up white light into the light spectrum that shows each different color. However, a rectangle does not have the edges needed to break the light up.
Why do lemons kept in a glass of water appear to be enlarged?
give reasons: 1) lemons kept in a glass of water appear enlarge. 2)dispersion cannot take place through a glass slab. 3)fuse wires or miniature circuit beakers are not used in a circuit containing electriccells why? 4)a stationary charge cannot produce electric field.
Why does light refract when it passes from air into a glass slab?
Because glass slab is optically denser than air.
Why does a ray of light passing through the glass slab not show dispersion?
White light is actually a combination of all of the colors of all of the rainbow. It splits in a prism because the prism can pick up the differences. However, it will not in a glass slab because the slab is smooth and will not reflect all of the different colors of light.
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.

Why glass ionomer cement not mixed on glass slab?
GIC has silicate 'GLASS' in it's powder and so while mixing on glass slab the polyacrylic acid attack the glass content of glass slab. This may even alter properties of GIC.
Why does light refract when it passes from air into a glass slab?
Because glass slab is optically denser than air.
Why air bubble in a glass slab have silvery look?
refractive index of glass is higher than refractive index of glass slab OR density of air is less than density of glass

Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
Refractive index of a glass slab using a travelling microscope?
To find the refractive index of a glass slab using a travelling microscope, you would first place the glass slab on a flat surface. Using the travelling microscope, measure the apparent shift in the position of the object when viewed through the glass slab. By knowing the thickness of the glass slab and the shift in the position, you can calculate the refractive index using the formula: Refractive index (n) = (apparent shift + 1) / actual shift.
In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
