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.
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!
The light that enters your eye carries enormous amounts of information with it. Your eye and a small portion of your brain comprise a highly specific tool for extracting a small subset of that information and processing it. The information you use is only related to the last object the light interacted with, not the light itself (with the small exception being the “brightness” - that has nothing to do with the object).
No one claims to hear the air in their ears rather than the violin that is being played nearby. That’s just not what the word “hear” means.
This is obviously false, otherwise all objects would look the same under any color of light - yet they don’t. This example actually shows that it is only the light itself that matters, because it has the information of the objects it interacted with during its lifetime!
But everyone would agree that we’re hearing the sound waves produced by the violin. Again, a great example counter to your point, as the equivalent to a sound wave is the photon.
Put your eye in the beam and tell me that again…
What
You can’t see light. You can see things illuminated by light.
You should have bolded this and done all caps.
You swap seeing with recognizing. You recognize things. And you see light.
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.
Bro, take the L and walk away. Seeing is a sense, senses are neurons activated by something, whether it’s; temperature, chemicals, or photons.
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.
It’s true! When it’s dark out it isn’t because there’s no light, but because you’re trapped in the void!
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…
And green lasers
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.
