![]() I would hope it would be against the code of even super villains. ![]() ![]() Thus Jessica could use X-ray radar on objects that are relatively close to her.Īnd if super heroine Jessica is battling the more powerful super villain Invincious and is losing she can use her X-ray radar on Invincious during the fight to ensure that Invincious will eventually get sick and die and no longer be a menace, if that is not against Jessica's code. Maybe Jessica Hill could generate some kind of force field behind whatever they were looking at, and the force field would reflect the X-rays that Jessica generates back at Jessica. X-rays are adsorbed by the atmosphere after travelling only a short distance, and the main natural sources of X-rays on Earth is the Sun, and solar X-rays are stopped by the miles of atmosphere, which makes it possible for life to survive on Earth. So Jessica Hill couldn't use natural X-rays in the environment to see through objects that were between the X-ray source and Jessica. Any substance that reflects X-rays well enough to be send a lot of X-rays back to the X-ray radar generator would probably reflect X-rays too well for its insides to be seen by X-ray radar. X-rRay machines work by putting the patient or object between the device that generates the X-rays and the device that records the image. But those X-rays would not be reflected back to the superheroes well enough for them to see anything. If superheroes emitted X-rays for X-ray radar the X-rays would not only be bad for human health but would go through many solid objects perfectly well. And possibly the "vision" in "X-ray vision" is equally metaphorical. ![]() It means that superheroes can see through objects just as well as if they were using X-ray machines. Thus the "X-ray" in "X-ray vision" is probably metaphorical. If superheroes emitted X-rays for X-ray vision it would be more like X-ray radar than X-ray vision. Maybe superheroes' X-ray vision doesn't use X-rays but something else. You're just collecting the information that's already there, in ways that no human can.Īnd, a related video, showing Wifi-frequencies radio waves being used to "see" people through walls and windows: AI Senses People Through Walls They'd see the string of communications satellites in geosynchronous orbit, arrayed like a string of pearls fixed to the sky in, and would be able to see these whether they were indoors or out.Īnd none of this would require our super-powered friend to do anything that would increase the chance of cancer in any of their friends, because vision is a passive ability. (They'd also see these power cables in various radio and microwave frequencies.) They'd see humans, computers, and other warm objects glowing warmly, even being able to see them walking behind thin curtains, and can tell when a power cable is actually supplying power through IR light. If the super power worked by expanding a person's ability to see more than just visible light, they would see Wifi transmitters as bright lights casting radio-light onto all of the metallic objects in the room, including the metal inside of various walls, like nails in studs, or steel rebar inside of concrete. This process is used in fluorescent lights to convert UV into white light, and in old CRT televisions to convert the stream of electrons accelerated by the cathode-ray gun into the images you see. Phosphorous will absorb UV light and accelerated electron, and re-emit it as visible light. Some objects react differently to different types of light. Different types of glass can be used to let IR and UV light through, as well. A household pane of glass lets visible light through, but blocks infrared and ultraviolet. They pass through you like bullets pass through paper targets.Ĭertain objects are transparent to different wavelengths of light. Gamma waves pass through nearly everything, but are also a form of ionizing radiation. The entire Electromagnetic spectrum includes gamma waves, X-rays, UV light, visible light, infrared light (which is very useful for seeing how hot an object is), and all of the ranges of radio waves, including microwaves.ĭifferent wavelengths of the EM spectrum pass through different objects in different ways, and affect different things in different ways, as well. What makes visible light special is that we have special sensors in our eyes that react to this EM radiation when it is at specific wavelengths - when they have certain amounts of energy. Light is, described more generally, just electromagnetic (EM) radiation. Human eyesight uses a very narrow range of all available light.
