Comment on British soldiers tune radio waves to fry drone swarms for pennies

  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 is literally activating the rods and cones based on photons hitting them. Do you think we don’t smell smells either?

        Ah yes, that’s famously why screens literally build tiny versions of the world inside them. We don’t see the light, we see the objects!

    Put your eye in the beam and tell me that again…

      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.

        You should have bolded this and done all caps.

        You see the light waves reflected off of various materials.

        You swap seeing with recognizing. You recognize things. And you see 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.
