Answer: Earth wire
Explanation: In the three-pronged plug , left pin is neutral and color of this pin wire is black, right pin is phase and color of this pin wire is red and third pin which is larger then other two is earth pin and color of this pin wire is green.
Third pin use for safety from the shock and to control high voltage of electricity.
So, the third wire in a three-pronged plug is called earth wire.

Using the formula v=f times lambada
then v=the speed of light.
and f=what’s we’re looking for
and lambada=the wavelength.
so then you sub what you have (v and lambada) in the formula.
then multiply the frequency(f) by the given wavelength and then solve for f
then v=the speed of light.
and f=what’s we’re looking for
and lambada=the wavelength.
so then you sub what you have (v and lambada) in the formula.
