  Also known as “light”, as used in Lasers, which also works to knock down drones.

    Radio waves are a specific wavelength/band of the EM spectrum. Light is not radio waves, just as radiowaves aren’t light.

    They’re both electromagnetic waves.

    Infrared lasers aren’t visible. They’re still higher frequency than radio waves. To say that visible light is visible radio is to say that the sky is green, just that it’s predominantly blue coloured green.

    Look around the space you’re in and notice that you can’t “see” the light, only the things.

      You don’t see the things, you see the light reflecting off of them

        Don’t look into the laser with remaining eye.

        That’s not what the word “see” means.

        It’s true! When it’s dark out it isn’t because there’s no light, but because you’re trapped in the void!

        You can’t see light. You can see things illuminated by light.

      Imagine if they showed real physics in sci-fi movies. You’d never see any laser blasts in space, just the result of their strike.

        You sure can see plasma cannons though…

    Lasers are more useful in surveillance and navigation and guidance and precision work in production, for a weapon they are, most of the time, out of place. Both expensive, unreliable and weak.
