Black Holes don't give off radio waves. They emit X-rays. This happens rarely since the black hole's gravity is so strong that it doesn't allow photons to escape.
Black holes do give off gravitic waves, but according to non-string theory, no a convergence of electromagnetic waves in space do not create a black hole.
Spectrum gives UV rays or waves besides the usage of the sun
Scientists "see" things through specialized equipment that identify waves that are invisible to a human eye i.e. microwaves, gamma waves, etc.Also because we are in the Milky Way, right? SO There are many stars in our galaxy. So, they can see it because it was a big black gap right in our galaxy and they could see stars flowing in it being sucked into it. Like when you drain the bathetub after a bubble bath. You can see the little torpido of water in it. Even when it's the same color. You get it?Black holes don't give off gamma rays or microwaves. That's the whole point. (Except hawking radiation, of course, but that is hard to detect as the effect is so small in large objects.) Seeing objects that don't reflect light is tricky business. And black holes are as mysterious as a target can be. Not even light can escape them. This is a pretty tricky problem for scientists, whose instruments usually rely on light-- whether it's visible light, radio waves, X-rays or infrared-- to observe objects in space.One method to see black holes has been to watch the fate of an object falling into one of these cosmic graves. If material actually falls into a black hole, it gets shredded apart and it heats up. As it heats up, it starts emitting light and this radiation we can observe. In particular, we can often see X-rays coming from black holes. When gas orbits around a black hole it tends to get very hot because of friction. It starts emitting X-rays and radio waves. So a lot of times black holes can be found and studied by looking for bright sources of X-rays and radio waves in the sky.These X-rays do not get through the Earth's atmosphere and can only be seen with telescopes positioned in space, such as the Hubble telescope.The strong gravitational attraction of a black hole affects the motion of nearby objects. When astronomers see a star circling around something, but they cannot see what that something is, they may suspect it is a black hole. Astronomers can even figure the mass of a black hole by measuring the mass of the star and its speed. The same kind of calculation can be done with black holes at the center of many galaxies, including our own galaxy, the Milky Way. In fact, at the very center of our galaxy, radio and X-ray telescopes have detected a powerful source called 'Sagittarius A', identified as this massive black hole.
Quasar actually means quasi-stellar radio sources so we thought that it was giving off radio waves but we did not put into account the redshift that causes the stretching of the wavelength meaning that it most likely gives off microwaves.
He discovered that black holes give off radiation.
While black holes give off radio waves, the fact that no light can escape, or be reflected off of, black holes makes them completely invisible to any regular light-capturing device.
Black holes do give off gravitic waves, but according to non-string theory, no a convergence of electromagnetic waves in space do not create a black hole.
uv rays can give u sunburns but radio waves cant
Spectrum gives UV rays or waves besides the usage of the sun
Yes.
Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
They give out gamma radiation as well as some incredibly low frequency sound waves, reaching up to 2 km in width
pulsar
As far as we know.
mobile phones give off radio waves to special stations which are built especially to connect calls, as they used to have an operator this is what now is used instead of the operator at this modernised age.
I had to think for this one but me being eleven I'm surprised nobody could answer but there are none on earth that i know of its in space a star, a star gives off radio waves.
Scientists can detect black holes by using x-rays and gamma rays. Black holes still can release matter, and black holes give off a lot off x and gamma rays.
