Answer 2

A photon torpedo is a torpedo weapon armed with an antimatter warhead. The Enterprise episode Sleeping Dogs reveals that the Klingons have had photon torpedo technology since as early as 2151. Photon torpedoes first appear on a Starfleet ship in the Original Series episode "Arena" as part of the USS Enterprise's armament. The key ships and installations in subsequent Star Trek spin-offs, other than Star Trek: Enterprise, are also armed with photon torpedoes.

Photon torpedoes appear as red,[9] orange,[10] yellow or blue blobs[11] of light when fired.

Furthermore, smaller Starfleet craft such as shuttlecraft and Runabouts can be armed with 'micro-torpedoes', a scaled-down version of photon torpedoes designed for use on craft too small to accommodate the full-sized torpedoes

Answer 3

It's about the size of a coffin, carrying a warhead of matter and antimatter, that annihilate each other upon impact, creating pure energy. Around the late 24th Century, they could have a variable explosive yield, of up to 200 isotons. They can be fired at either normal space or while in warp.
