Index of Refraction

What spookman117 said, but in better grammar:

Pyrex and Oil have approximately the same index of refraction (how much the medium 'bends' light, or makes it change speed), and so light passes through both pyrex and oil in the same way. Light passes through as if there was no medium change at all, making the pyrex stirring rod seem 'invisible.'

Can anyone answer this:

Why is it that, when two mediums that have a similar index of refraction, no image is formed? What makes it invisible to the eye?

@VipericVampire

it works because as the light passes between the two objects since they have the same index of refraction the light acts like it didnt chance medium so no light reflects off the second medium so you cannot see it.

Well this is how it works:

Index of Refraction for the OIL and PYREX is same that the light rays dont refract because the medium is very similar (due to the index of refraction) and hence the pyrex glass looks invisible... there are some angles that you could see the glass with but for the first time, its never easy to see! which is wat makes it so exciting for students...

i dont know how it tells anything about refraction but im GESSING its that oil blocks light

[spookman117]

@scifregizmoguy nope

it works because as the light passes between the two objects since they have the same index of refraction the light acts like it didnt chance medium so no light reflects off the second medium so you cannot see it.
