refraction is the bending of light rays when they pass through an object
reflection is the light energy that bounces off objects
Optical telescopes are of two types: refractive and reflective. The refractive telescopes have chromatic aberration (huh? different colors are focused in different plains -- huh?). This is less of a problem with reflective telescopes.
No. A Dutchman created a refractive telescope. Newton improved the telescope by creating the Reflective Telescope.
Impurities can cause a significant change in the reflective index of a liquid. Impurities totally affect the results of the experiment. It changes the reflective index and affect the concentration of the solution.
Crystaline sugar (sucrose) has a refractive index of around 1.56. Sugar solutions can have refractive indices greater than this. Note, that the refractive index of a substance can even be determined for opaque substances. This is because the RI also determines reflective properties. So by measuring the amount of light reflected by light shining on a polished sample at a given angle, a refractive index can in principle be obtained.
I cannot answer this question without knowing the numbers for the glass

The cut of a diamond is what gives the mineral contained within the stone its access to reflective and refractive qualities of light. If a diamond is poorly cut, it will not have the 'fire', or dazzle of a well-cut stone.
Refractive index of vacuum is 1.
Refractive Index: 1.4465
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
If the surface is completely reflective then the angle at which the incident light leaves the surface will be different. For a rough surface the light would be scattered, whereas for a smooth surface they would reflect at the same angle the hit. If the surface isn't completely reflective then the angle and speed and which the light enters the object. For a rough surface the angles will random and based on the refractive index of the material. For a smooth surface they will be proportional to the sin of the angle times the refractive index.
Diamonds are rare, difficult to find, mine, fashion and expensive to buy. Diamond as the advantage of being totally engaging to the human eye, because of its reflective, refractive and natural colour.All these elements combine to make diamond a gemstone.Yes.
