Hi new physicists! Here is a video of our experiment which we carried out last day.

Hi Physics lovers!
Use the simulation above to find the frequency of the passing waves.
Press the UP Green arrow to start the wave motion. Pressing it again increases the wave speed while pressing the down arrow will reduce the speed.
If the waves run out just press the pause button and then the RESET button.

ANSWER FORM

This is a fantastic piece of simulation software from PhET which allows you to build electric circuits and study what happens when you change resistance or voltage.

Download the simulation by clicking on the picture.

To get you started why don`t you build this circuit
Investigate:

1. How the current in the circuit changes when the 8 ohm resistor is doubled
2. How the voltage will change across the 24 ohm resistor when the 8 ohm resistor is doubled.

Have some fun building more circuits and investigating the the current, voltage and resistance of the circuit.
