(a) glass slab: It deviates from the actual path but the direction of incident ray and the emergent ray remain parallel. (b) glass prism: The splitting of white light into its constituents seven colors occurs and the direction of incident rays and emergent rays are not parallel to each other. (ii)

it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.

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 a glass slab not disperse white 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 occur in prism but not in a glass slab?

Because the faces of the glass slab are parallel,whereas the faces of the prism are not.

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?

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 glass slab does not produce dispersion?

surface tension

In which medium will a lens behave as a glass slab?

the medium which have the same refractive index as glass.

How does lateral displacement change with the width of a glass slab?

, this is ojashwin mishra---- lateral displacement increases with the increase in thickness of the medium. it doesnt have any relation with the width of the glass slab

Why glass slab do not causes disperssion of light ray?

Glass does cause disperssion. Think of a prism.

When light travels from air into a glass slab there is no change in its?


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.

What will happen when ray of light passes through a glass slab?

speed of light will decreases

Why emergent parallel incident ray in a glass slab?

This is because the amount of refraction taking place at the parallel faces of a glass slab is equal but opposite and since the faces are parallel the emergent ray emerges parallel to the incident ray with lateral displacement.

Why white light spilts into different colours when it passes through prism but does not split when passes through glass slab?

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 light refact when it passes from air into a glass slab?

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

How should a ray of light be incident on a glass slab so that it comes out from the opposite side of slab without being displaced?

The question is phrased very poorly, as the photon is by definition displaced after traveling through the slab. If you meant "deflected", however, it must be normal.

How do you determine refractive index of a glass slab?

By using travelling microscope and formula n=h/h'

What happens if light is passed through a glass slab whose sides are not parallel?

What happens to the wavelength of light when a ray of light enters a glass slab from air?

Why there is no dispersion of light refracted through a rectangular glass slab?

Different wavelengths take slightly different paths through the glass but the dispersion on entry and exit cancels out.

What is the focal length of a rectangular glass slab?

Infinity, as rays after refraction neither actually nor appears to meet.

What is a refraction of light with a glass slab?

Bending of light when it travels from a rarer to a denser medium it bends towards the normal

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.
