Red light.
Blue light travels faster in crown glass compared to red light.
window, because sound travels fastest through solids, liquids second, and gases last.
Sound travels faster through aluminum than glass because aluminum has a higher speed of sound due to its higher stiffness and density compared to glass.
Light travels faster in air compared to glass because the speed of light is inversely proportional to the refractive index of the medium. Air has a lower refractive index than glass, so light can move faster through air than through glass.
Light travels fastest in a vacuum because there are no particles to slow it down. It slows down in air, even more in water, and even more in glass due to interactions with particles in those mediums.

The denser the medium, the faster sound travels through it. Glass (silicon oxide) is fairly dense, and sound waves propagate through it faster than they do through air or water.

True
Light travels faster in air compared to glass because the speed of light is inversely proportional to the refractive index of the medium. Air has a lower refractive index than glass, so light can move faster through air than through glass.
true
Yes, that is correct. (Slower than in a vacuum.)
No
No
Light travels fastest in a vacuum because there are no particles to slow it down. It slows down in air, even more in water, and even more in glass due to interactions with particles in those mediums.
Light travels fastest through air, then glass, and slowest through water. The speed at which light travels through a medium depends on the refractive index of the material, with lower refractive indexes resulting in faster speeds.
