According to the density of the given substances, the order in which white light passes through these substances, from fastest to slowest is Y < X < Z < W. So, it's D.
What is Density?
Density may be defined as the mass or quantity of substances in a unit volume. It describes the compactness of any substance.
The intensity of light passes is inversely proportional to the density, which means density decreases, and the intensity of light passes increases.
Therefore, the correct order is Y < X < Z < W.
