If ghosts? Well, think very carefully before choosing this option

There will be ghosting but because of the attenuation
in the 450 ohm series resistor, the ghosting will be
below the level detectable on a TV screen by the human
eye.

It would be much more convincing if you were to compute the
magnitude of the ghost rather than handwaving an answer.

Though when you do so, you will find that it is exactly zero,
so be prepared.

its all ghosts and mirrors!

forget power, forget energy, they are products of other calculations. all
that is needed is impedance and voltage OR current. once you know voltage
OR current and the impedance you can calculate all the rest.
