Refraction of light occurs when a light pass through a glass that is filled with water. In this process, the light changes direction as it changes transmission medium.
When you dip a glass upside down in a pail filled with water, the air trapped inside the glass creates an air pocket at the top of the glass, preventing water from entering. This is because the pressure of the air inside the glass is greater than the pressure of the water outside. The glass will remain filled with air and no water will enter.
Objects will look larger when viewed through the side of a water-filled glass due to refraction. Light bends as it passes through the water and then again when it enters the air, causing the object to appear magnified.
Sunlight is slowed the most when traveling through a medium with a high refractive index, such as glass or water. This is due to the increased interaction between the photons of light and the atoms in the medium, causing the light to bend and slow down.
When light hits a translucent glass, some of the light is transmitted through the glass, some is absorbed by the glass, and some is scattered within the glass. This scattering causes the light to appear diffused rather than simply passing straight through.
Light that does not enter the glass block will either continue traveling through the air or be reflected off the surface of the glass block. The reflected light may create a reflection or be absorbed by the surroundings.

The water should evaporate if the glass was not covered.
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.

the light slows in speed and refracts due to glass being denser than air.

I would stick my mouth in the center of the glass and sip for about 15-20 seconds and then your glass won't be filled to the brim
Light travels through what is fiber optic cabling. The cables are internally filled with long flexible tubes that are made of glass. The laser light travels through an individual glass tubing.
