Light cannot go though a wall- that is why you cannot see through a wall. Well, you CAN- if there is a window in the wall.
Air.
Air.
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 waves travel faster through air than through water because air has a lower refractive index than water. This means that light waves experience less bending (refraction) in air compared to water, allowing them to move faster.

glass
Light travels faster through air than through oil. The speed of light is slower in a medium like oil, due to its higher refractive index and denser molecular structure, which causes more interactions and delays in the light propagation.
Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.
Any electromagnetic wave that can propagate through water at all will do so at a lower speed than when it's in air.
Air.
An opening in a wall to let in air or light is called a window.
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
