correct answer please!
10. I want to create an electromagnetic wave. What is the best way to do this? (a) Nothing - electromagnetic waves can be transformed, but can never be created or de- stroyed (b) Use a Poynting vector (c) Pass unpolarized light through a polarizer. () Use either a parallel plate capacitor or a solenoid with the right type of current. (e) Oscillate an electric dipole (flip the positive-negative direction) back and forth.
