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 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
Lead monoxide is used to increase the refractive index of glass.
the medium which have the same refractive index as glass.
Everything a lens does is the result of the change of refractive index at its surface.If the lens is surrounded by a medium with the same refractive index as the glass,then there is no refraction (bending) of light at the glass surface, and the lens is nolonger a lens. If you could find such a liquid, you might not even be able to see thatthere's a lens down there in it.

Refraction is the redirection of light. Refractive glass could be a number of things. Care to elaborate?
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 in=__________sin r

To find the refractive index of a glass slab using a travelling microscope, you would first place the glass slab on a flat surface. Using the travelling microscope, measure the apparent shift in the position of the object when viewed through the glass slab. By knowing the thickness of the glass slab and the shift in the position, you can calculate the refractive index using the formula: Refractive index (n) = (apparent shift + 1) / actual shift.
Lead monoxide is used to increase the refractive index of glass.
refractive index of glass is higher than refractive index of glass slab OR density of air is less than density of glass
