Much better than those visible radio waves.

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. Microwaves are another specific wavelength.

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.

[–] [email protected] 25 points 4 days ago (2 children)

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

[–] [email protected] 6 points 4 days ago

Don't look into the laser with remaining eye.

[–] [email protected] 9 points 4 days ago

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!

[–] [email protected] 1 points 4 days ago (3 children)

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

[–] [email protected] 1 points 3 days ago

You should have bolded this and done all caps.

[–] [email protected] 7 points 4 days ago (1 children)

You see the light waves reflected off of various materials.

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.

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

[–] [email protected] -3 points 3 days 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.

[–] [email protected] 3 points 3 days ago (1 children)

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

take the L and walk away.

I'm here having reasoned conversations with thoughtful people. I left the karma farming behind on reddit, and I don't miss it. I can't lose.

The word "see" predates the concepts of neurons, chemicals, and photons by thousands of years. We see objects, not 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.

[–] [email protected] 2 points 4 days 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.

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.

[–] [email protected] 9 points 5 days ago (2 children)

Invisible weapons are all the rage these days.

[–] [email protected] 7 points 5 days ago

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

[–] [email protected] 3 points 4 days ago

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

You overestimate the education of the average person
