Question

Refractive index of combination of glass and water is

Answer 1

some typicall refractive indices for yellow light (wave length equal to 589 nanometer are the following water 1.333crown glass 1.517; dense flint glass, 1.655; and diamond, 2.417. The variation of refractive index with wavelength is the source of chromatic aberration in lenses.

Answer 2

-Hey there!

-Here is the answer for your question :

Refractive index of :

Crown glass : 1.52 - 1.62

Spectacle crown : 1.523

Water : 1.333

Combination of glass and water =

1.52 + 1.333 = 2.853

1.62 + 1.333 = 2.953

You didn’t mention any type of glass.
