Nothing. the speed of light is a scalar constant. Space can't expand however without creating energy. If it is true that energy can not be created or destroyed, then space can't change, expand or contract.
Diffraction is the process of how a beam of light is spread out when passing through a narrow space or edge. There is usually interference between the wave forms.
Light cannot pass though matter but matter is technically atoms, which are mostly space with a few, moving objects - electrons and the nucleus. For glass, the loss of light through the material occurs for all glass.
Light travels fastest through empty space.
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.
While passing through glass.
Perfusion - passing of a fluid through space

Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.

1. - It is refracted (bent) relative to the source. 2. - The spectrum is separated, the amount depending on the thickness and curvature. 3. - A small part of the light is reflected off the lens, not passing through it. 4. - Assuming a 'perfect' regular (convex) lens, all light passing through the lens focuses at a single point in space, (focal point). 5. - Any image passing through the lens is reversed, equidistant from the focal point.
Light travels fastest through empty space.
Light can travel through any parts of space, there is no part that it is excluded from.
