Shorten the jamming signal's wave-length... to the same frequency.

The stones wave-length shortened again. Shorten the jamming signal.

The stones' wave-length is approaching visible light.

Pushing the wave-lengths this short... is turning Stonehenge into a nuclear reactor.

Since we also see along the same frequency... visible light wave lengths, the door would also seem to disappear.
