If laser weapons were real, they would not experience bullet drop as real guns do. Bullet drop occurs due to the gravitational pull on projectiles such as bullets, causing them to gradually lose altitude over distance. However, lasers are beams of light that travel at the speed of light, and they do not follow a ballistic trajectory like projectiles fired from firearms.
In theory, lasers would maintain their accuracy over long distances because light travels in a straight line unless affected by other factors like atmospheric conditions or obstructions. Therefore, a laser fired from a weapon would not experience the same kind of drop or deviation that a bullet does.
That being said, it's important to note that laser weapons as depicted in science fiction often take liberties with the laws of physics. While lasers themselves would not experience bullet drop, other factors, such as the dispersion of the laser beam due to atmospheric conditions or the divergence of the beam over long distances, could still affect the accuracy and effective range of a laser weapon.
