| Amplitude Meter: The amplitude meter measures the amplitude of waves generated in a Ripple Tank at the location of the meter's detector (the crosshairs in the picture below). You can place up to ten meters anywhere in the simulation window. The meter appears at the point you click. The detector appears in the center of a Ripple Tank if you click inside a tank, or in the center of the simulation window if you don't. In the meter's Properties Box, you can set the maximum value for the amplitude bar scale. You have full access to amplitude meters during both Stop mode and Run mode.
With the Select tool, you can move the amplitude meter. Separately, you can select and move the detector. You must click-and-drag on the detector's handle, located in the middle of the crosshairs. Moving the meter also moves the detector, but the reverse is not true. |
When you place an amplitude meter on an object (other than a graphics object), the meter remains connected to that object. Thus, if you place an amplitude meter in a Ripple Tank and move the tank, the meter will move with it. The meter will also move with a clock, however, if you place it on one!
