Is refraction of light is depend on density or volume?

Refraction of light primarily depends on the density of the medium rather than its volume. When light passes from one medium to another, its speed changes due to the difference in density, which causes the light to bend. The refractive index, a measure of how much light slows down in a medium, is related to the medium's density. Therefore, while volume itself is not a direct factor, the density of the material plays a crucial role in determining the extent of refraction.
