Why does light refract when it passes from air into a glass slab?
Because glass slab is optically denser than air.
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.
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.
What will happen when ray of light passes through a glass slab?
speed of light will decreases
Why glass slab do not causes disperssion of light ray?
Glass does cause disperssion. Think of a prism.
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 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 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.
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
When light travels from air into a glass slab there is no change in its?
direction
What is glass slab?
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.
