Cutting wedges of grinding wheel are positioned in resonance ultrasound wave systems antinodes of longitudinal stagnancy oscillation. |
The antinodes alternate in the direction of displacement so that the rope at any instant resembles a graph of the mathematical function called the sine. |
If two of the three indices are zero, then the pressure antinodes of the associated mode form planes. |
As the speaker volume increases, the difference between nodes and antinodes becomes easier to hear. |
Not only do the vibrations go up and down from the ends of the air column to the nodes, but also between the nodes, with maximum velocity at the antinodes. |
Very similar to a coffee cup, whose nodes and antinodes are determined by the location of the handle. |
