The bottom flat valve is to suck the water for the pond. The above flat valve is to push out of the tube.
The engineers used the same way to build Hong Kong Airport base.
The ambulance produced the sound wave, pushed the wave bonded together, changed frequency, and created the higher pitch of sound. As the ambulance ran away, the sound wave stretched out and the pitch changed again.
Wind Shear Warning System. Monitor the droplets in the air, usually the rain.
The radar wave bounced off the wet droplets back to the tower, the airport can tell whether the
cloud are moving away or toward to the radar by measuring the changing of frequency, just like
the sound wave. But what if the water droplets is too small to detect or the air is too dry ??
How to detect the invisible threat ??
Use the light to detect the particle of the air.
Use the laser to detect the wind shear.
