People need to use a little more common sense and actually take biased blinders off. This was actually one of the best decisions of the WC, and the 3rd umpire read the ultra-edge graph beautifully. The wave runs from left to right.
The wave shown here is at end of the time frame. Which means it is registering the sound that occurred very very very slightly before the freezeframe. That is the sound of the bat hitting the ground. The bat had hit the ground and was on its way up already, hence the gap.
The wave CANNOT be the ball hitting the bat because that wave would first register on the left side of the time frame, not the extreme right side. Learn to read ultra edge/sound graphs first. Then pass judgments. If you can’t read them, stay silent.
It was a bat hitting the ground. These side-by-side images are not taken in identical split seconds.
1. Check the spot on the ball on the left of the featured image. It is almost in front of the percussion but on the right side, it is facing the side camera view.
2. The bat on the left is at the inclined point. Check the bad is vertical (90 degrees) on the right pic.
