Does the velocity of a wave that originates in air increase as it changes mediums and travels through a solid?
When a sound wave begins in air, does the velocity of the wave increase as it moves into a different medium, namely a solid?
When you give your answer please give some credibility to your answer like a source or your own credentials.

yes it does. sound waves travel faster in denser materials (eg the speed of sound in water is approximately 3 times that of sound in air) mainly because in a higher density material it is easier for one partical to hit the next and allow the wave motion to carry on. you can test it yourself. if you find a long enough metal pole and put one ear on it, and have someone strike the pole at the other end, you will hear the sound in the ear pressed to the pole a fraction of a second earlier than with the other ear.
