What happen if refractive index of glass is same as that of air?

then we wouldn't be able to identify from air and glass at all, since light would pass through glass without deflecting at all!!

In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
What happens if the refractive index of glass equals to the refractive index of air briefly?
When light passes from one substance to another, and both have the same refractive index, then there will be no refraction - or change of direction - at the border. It is as if there were only one substance.
What will happen when two different medium of same refractive index?
The angle of incidence will equal the angle of refraction. If two medium have the same refractive index, light does not bend.
Will the focal length of glass lens change when dipped in liquid of refractive index equal to glass?
Everything a lens does is the result of the change of refractive index at its surface.If the lens is surrounded by a medium with the same refractive index as the glass,then there is no refraction (bending) of light at the glass surface, and the lens is nolonger a lens. If you could find such a liquid, you might not even be able to see thatthere's a lens down there in it.
What is refractive index of AIR?
1Ideally speaking, the ratio of the sines of the angles of incidence and refraction will be the same if the medium is the same. So the refractive index will be 1.However, refractive index is, again, a relative value. If we say that the refractive index of glass is 1.5, it implies that the refractive index of glass, with respect to air is 1.5. So the value might change based on the media involved in refraction.It can also be safely concluded, without much Physics, that any multiplicative quantity for the standard element will be 1. (ex: speed of sound is Mach 1)
Is the refractive index of glass the same for all colours of light?
No.
Why Glycerin is not visible when kept in Glass bottle?
Because it has the same refractive index as glass.

Relation between refractive index and refractive power?
The refractive index and refractive power are both directly proportional becausedue to power the distance is decrease or increase if power increases or decreasesand to refractive index the bending of light occurs in towards or away. Bending oflight ray and distance of light ray are directly proportional so refractive index andpower are directly proportional.==========================Answer #2:They have very little connection, except that the same big word appears in both terms.Refractive index of a substance is the ratio of the speed of light in vacuum to thespeed of light in that substance.Refractive power of an optical device, like a lens, does naturally depend somewhaton the refractive index of the material used to make the lens, but it's got muchmore to do with the shape of the lens ... the curvature of its surfaces etc.You can make lenses with a wide range of different refractive powers, all out ofthe same kind of glass with the same refractive index. And you can constructlenses that all have the same refractive power out of many many differentsubstances with different refractive indexes, like crown glass, flint glass, plastic,jello etc. So in that sense, the two are completely unrelated.
What would be focal length and power of a glass when it is dipped in liquid of refractive index equal to glass?
Lenses operate on having another index than the immediate surrounding. Sink a lens in a media with the same index and it won't work. It'll be like it's all glass.
What would occur if water were accidentally used in place of immersion oil?
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
How does the speed of visible light compare with the speed of gamma rays when both speeds are measured in a vacuum?
The speed of light in glass is the reciprocal of the refractive index of the glass or 1/(refractive index). Not all glass is the same: its refractive index can range from less than 1.5 for Pyrex (a borosilicate glass) to more than 1.9 for (impure) flint glass. This means the speed of light in glass can range between 0.52 and 0.68 of its speed in vacuum.
How is a wave changed by reflection?
When a wave traversing in a medium of less refractive index gets reflected at a medium of greater refractive index then wave undergoes a phase change of pi radians. But if the same reflection takes place as the wave traverses from a medium of greater refractive index to that of less refractive index, then no such phase change. The later reflection is known as total internal reflection. So as light traversing in air gets reflected at glass then phase change of pi radians occurs.
