Turn off the second drip and then at a barrier with one slit. What do You observe on the right side of the wall? What do You observe enough side of the wall? From a physics perspective, explain your observations of what is happening on both sides of the barrier.

Idon't know it i just need my points lol

Sorry i don’t know what to do

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
