The of a black hole in a binary system can emit X-rays and allow us to detect the presence of the black hole?
It is possible to detect black holes by the X-rays emitted at the event horizon. That's one way to "see" them. It's tricky, but the tools of the modern astronomer are nothing short of astonishing. Let's take a walk.
Lots of times we think of telescopes as instruments through which bleery-eyed investigators peer for hours on end. It ain't like that now. In addition to the optical telescopes we know of (which now have CCD imaging equipment at the focal point and computers to look at the pictures), we have "eyes" pointed at the sky that can see across the electromagnetic spectrum, including X-rays.
The X-rays generated at the event horizon of a black hole appear as the result of the acceleration of gases into the gravity well. And we have things like the Chandra X-ray Observatory to see such things. Chandra launched in the summer of '99, and by the 2000's, stunning images were beginning to amaze observers. Including things like X-ray emission from Sagittarius A's supermassive black hole, which is at the center of the Milky Way.

What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
How long does it take for Xrays to travel from the Sun to the Earth?

Do solar flares prouduce xrays and radio waves and clouds of atomic particles?
Because of the radiasion
Which types of electromagnetic radiation can be detected using telescopes on Earth?
Telescopes on Earth can detect a wide range of electromagnetic radiation, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Different telescopes are designed to detect specific wavelengths within this range, allowing astronomers to study various objects in the universe.
What can postal xrays see?
Postal x-rays can detect the presence of items such as drugs, weapons, explosives, and other prohibited materials within packages and letters. These x-ray machines provide security measures to help protect against illegal or harmful substances being transported through the postal system.
What do xrays have to do with the holocaust?
They experimented with xrays on the prisoners in the concentration camps. Mostly at Auschwitz.
How much does a series of knee xrays cost?
I just got my xrays taken for my left knee, it was four xrays for $100, it may be more other places
Bad when pregnant and take xrays?
Xrays are damaging to developing babies. Only as last resort.
What do you call a person who does xrays?
a person who translates your xrays is called a radiologist.
If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?
No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.
Did they have xrays in the civil war?
No, they did not.
How do X rays detect bone cancer?
X-rays only show up dense areas in the body such as bone. An x-ray may show tumors in the lung as they show up as dense white patches and they can show bone erosion in people with bone tumours but they can't show up tumours which are the same density as the surrounding organs such as liver or kidney tumours. Similarly some cancers are carried in the blood or lymphatic system and these will also not be distinguishable on an x-ray. Other procedures can be used to outline these tumours, such as the use of x-ray dyes, CT scans or ultrasounds.
How does a nurse use math in x ray?
They dont, nurses dont take xrays! Radiologic technologist take xrays!
What instrument is used to detect xrays?
A device called an X-ray detector is used to detect X-rays. This detector can capture the X-rays that pass through an object and create an image that can be viewed on a screen. Popular types of X-ray detectors include film detectors, phosphor plate detectors, and digital detectors.
