No, if the refractive indexes of the two mediums are exactly identical it will be invisible.

What is refracting index of a medium?
Refractive index of the medium is defined as the ratio of the velocity of light in vacuum to that in the medium. No unit for refractive index.
The ratio of the speed of light in a medium to the speed of light in a vacuum is called its?
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
What is a deviation of light passing from one medium to another known as?
refractive index
Differences between relative refractive index and absoulate refractive index?
Refractive Index(i) Refractive index of a medium is that characteristic which decides speed of light in it.(ii) It is a scalar, unit less and dimensionless quantity.(iii) Absolute refractive index :When light travels from vacuum to any transparent medium then refractive index of medium w.r.t. vacuum is called it's absolute refractive index i.e. vacuumµmedium = c/vAbsolute refractive indices for glass, water and diamond are respectively µg = 3/2 = 1.5, µw = 4/3 = 1.33 and µD = 12/5 = 2.4(iv) Relative refractive index :When light travels from medium (1) to medium (2) then refractive index of medium (2) w.r.t. medium (1) is called it's relative refractive index i.e. 1µ2 = µ2/µ1 = v1/v2 (where v1 and v2 are the speed of light in medium 1 and 2 respectively).(v) When we say refractive index we mean absolute refractive index.(vi) The minimum value of absolute refractive index is 1. For air it is very near to 1. ( 1.003)
How do you calculate speed of light wave with refractive index?
The speed of light in any medium isspeed of light in vacuum/refractive index of that medium.
What is the refractive index of a substance?
It is the extent of the change in the direction of light as it passes from one transparent medium to another.
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.
What is light refracted by?
Light is refracted by a discontinuity in the refractive index of the medium ... by going from one medium into another one where the speed of light is different.
What does relative refractive index tells?
The relative refractive index tells the speed of light in a vaccum over the speed of light in medium.
In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
What indicates how much a medium can change the direction of light?
It is indicated by the refractive index of the medium.
What is relative index?
The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.
