Why does an object disappear when it is placed in a liquid of refractive index equal to or greater than that of the object?
The Attempt at a Solution
Well, I was just baffled by the problem. Finally, i came up with an answer: we see objects when they refract or reflect light. When refractive index of both are equal, there will be no refraction and hence the object won't be seen. However, i could not make out what happens to reflected light or what happens when refractive index of liquid is greater. Please help me out, if necessary you can use math.
