[Star Trek] What is the effective range of a phasor?
gpt
Yay for Starfleet Technical Manuals.

 On the type 1 phaser they were: stun - thirty meters, heat - two meters, disrupt - twenty meters, dematerialization - ten meters. On the type 2 phaser the ranges were: stun - ninety meters, heat - six meters, disrupt - sixty meters, dematerialization - thirty meters. Setting dials on the hand phasers indicated nine settings on the type 1 phaser and fifteen on the type 2 phaser, of which all above ten were labeled by the letters A through E. The letters might be a reference to the disruptor-B setting mentioned in "Obsession", which would make it setting 10B. According to Mr. Scott's Guide to the Enterprise, the hand phasers used during the first four movies had only three preset levels: stun, disrupt, and dematerialize.
