You can investigate fraction in glass using a rectangular glass block. By tracing the rays of light on a piece of paper, you can measure the angles of incidence (i) and refraction (r). If you repeat this process for a range of different angles of incidence, you would find that the sine of the angle of incidence and the sine of the angle of refraction are constant. This ratio is called the refractive index of the material, and is given the letter n.
The angles of incidence and refraction are related by the following equation:
sin i
n=__________
sin r

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)

What happens when light hits a bent piece of glass?
Some of the light is reflected off the glass at the same angle - in a manner and angle similar to that of a ball deflected off a surface at a similar angle. This is what happens when light reflects from car windows into our faces. Much of the light, however, will penetrate the glass, so that the light source is seen from the other side. Nevertheless, on contact with the glass, the light that penetrates will be refracted (bent) and travel through the glass at a different angle from that of its original contact with the glass; but once having travelled through the glass, it will leave at its original angle of contact. The amount of refraction depends on a number of factors, but especially, on the thickness of the glass and specific angle of contact involved. So, the light bends as it passes through the glass, but leaves at its original angle.

How do you perform an experiment to find the refractive index of a glass block?
To find the refractive index of a glass block for a particular wavelength of light, shine a beam of light of that wavelength through a material for which the refractive index n1 is known onto the glass block such that the angle between the beam and the block's surface θ1 is between zero and 90 degrees. Measure the angle between the part of the beam that enters the block and the block's surface θ2 and use Snell's law:n2 = n1 cos(θ1) / cos(θ2).Note: Typically Snell's law is expressed in terms of the angle between the beam and the direction normal to the interface and there for sines are used instead of cosines, but the use of cosines allowed the question to be answered without assuming knowledge of the concept "normal" to the interface.
The refractive index of water is 43 and for glass it is 32 with respect to airwhat is the refractive index of glass with respect to air?
"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
