The speed at which a wave travels is called its velocity. This velocity is typically determined by the frequency and wavelength of the wave.
Light bending away from its original path instead of returning towards the observer is known as refraction. Refraction occurs when light travels through different mediums with varying optical densities, causing its path to change direction.
We call the distance the wave travels in a given amount of time its wavelength. This term is commonly used in physics to describe the spatial period of a wave.

That is called a light-year.
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.
