• The index of refraction of glass varies with its composition and with the wavelength of the light incident on the glass. Ordinary crown glass, when illuminated by white light, has a refractive index of 1.52; medium flint glass has an index of 1.63, acrylic is 1.49.

• This system is called Glass Refractive Index Measurement (GRIM). Glass placed in different types of oil. Video of a fragment of glass placed in water sunflower oil and clove oil. You should be able to see that the glass appears to disappear in the clove oil. In water you can clearly see the glass but in the sunflower oil the edges of the glassstart to diappear . In the clove oil they cannoot be seen when the piece of glass is stationary. It is easier to show this as an animation.

• The index of refraction for crown glass is 1.512 at a wavelength of 660 nm (red), whereas its index of refraction is 1.530 at a wavelength of 410 nm (violet). Expert Answer.

Refractive index. Some typical refractive indices for yellow light (wavelength equal to 589 nanometres [10 −9 metre]) are the following: air, 1.0003; water, 1.333; crown 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.
