There's a Voyager epsiode where they fight the Borg. They fire the Phasers at the Borg. You know beam of light goes from Voyager to Borg ship then stays for a little bit too long. The Borg ship then pulsed back along the beam to Voyager. Cue sparks and such. Someone says

"What happened"
and 7 of 9 says
"They reversed the beam with a feed back pulse"

Is it really technobabble when that makes perfect sense? I mean the pulse goes back in the opposite direction and damages the emitters. Looks like a feedback pulse to me.

In fact it makes so much sense I would expect Star Fleet to plan against that tactic. Don't leave the Phaser beam in place so long, or use disruptors. Except that the disruptor beam would leave an ionisation trail and due to the need to align the disruptor pulse to pass through the ships shields that would leave a trail that could penetrate the shields in return.
