Light speed slows down in the glass.
glass
The answer depends on the medium which it then travels through.
light is refracted when it travels through air and then through glass
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass

It decreases.
Light does not change speed when it goes through glass.
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.
