Which type of wave can travel without a medium

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.
