Hi dear friends, I am Maziar Bahiraee a chemical engineering graduate. I had a question about one of my last inventions and I found that friends this group are specialized in this field. Q: After a wave with specific parameters encounters an obstacle, which of the parameter(s) is changed and how this change parameter(s) can be measured and what device can calculate the destination between the obstacle and the device. By the wave this obstacle is not a barrier kind. For example, assume this wave is moving on a paved road and hits a speed reducer (as an obstacle) which of the wave parameters will change after the hit?
