Much better than those visible radio waves.

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

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.

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

They're both electromagnetic waves.

Look around the space you're in and notice that you can't "see" the light, only the things.

[–] Fisch@discuss.tchncs.de 25 points 2 days ago (2 children)

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

[–] AnUnusualRelic@lemmy.world 6 points 1 day ago

Don't look into the laser with remaining eye.

[–] milicent_bystandr@lemm.ee 8 points 1 day ago

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

[–] Caitlyynn@lemmy.blahaj.zone 4 points 2 days ago (2 children)

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

[–] Tetsuo@jlai.lu 1 points 2 days ago (3 children)

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

[–] YiddishMcSquidish@lemmy.today 1 points 9 hours ago

You should have bolded this and done all caps.

[–] dubyakay@lemmy.ca 7 points 2 days ago (1 children)

You see the light waves reflected off of various materials.

[–] DrunkenPirate@feddit.org 4 points 1 day ago* (last edited 1 day ago)

That’s it. And, indeed, you see light. That’s what your eyes do.

Little smart ass knowhow: With your hands, you can feel light.

You feel infrared light as heat. Not visible light though. Just heat up your cooker stove and it emits a bit visible red and a lot infrared light. Don’t touch just keep your hand close to the stove. Now you feel the IR-„light“.

Or just take an IR-lamp for your neck pain. You‘ll feel the light that’s emitting with your hands.

[–] DrunkenPirate@feddit.org 4 points 1 day ago (1 children)

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

[–] tate@lemmy.sdf.org -2 points 11 hours ago (1 children)

That's not what the word "see" means. You're trying to to swap it for another word like "sense." You see objects, not light.

[–] YiddishMcSquidish@lemmy.today 2 points 9 hours ago

Bro, take the L and walk away. Seeing is a sense, senses are neurons activated by something, whether it's; temperature, chemicals, or photons.

[–] SocialMediaRefugee@lemmy.world 3 points 1 day ago (1 children)

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.

[–] Zoot@reddthat.com 2 points 1 day ago (1 children)

You sure can see plasma cannons though...

And any color light saber. Regardless if there's particles in the surrounding atmosphere or not.

[–] rottingleaf@lemmy.world 1 points 2 days ago* (last edited 2 days ago)

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. Expensive, unreliable and weak.

[–] FenrirIII@lemmy.world 3 points 1 day ago

You overestimate the education of the average person

[–] evilcultist@sh.itjust.works 9 points 2 days ago (2 children)

Invisible weapons are all the rage these days.

[–] Deceptichum@quokk.au 7 points 2 days ago

Have I got a box of invisible rocket launchers to sell you.

Damn. We gotta close the missile gap eith the six-year-olds.
