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.
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.
The way astronomers find black holes Is by using x-ray imaging from one of the many types of telescopes that orbit the earth. Black holes give off an incredible amount of x-ray waves. This is the only evidence I know of they use.
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.
Some artificial sources that can emit UV rays or waves include UV lamps, tanning beds, welding arcs, and certain types of light bulbs and lasers. These sources can potentially emit harmful UV radiation and proper precautions should be taken when exposed to them for prolonged periods.
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.

uv rays can give u sunburns but radio waves cant

Yes.
Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
Gravitational waves offer a way to study black holes and their surroundings by detecting the ripples in spacetime caused by their movements and interactions. This allows scientists to observe events like black hole mergers and understand the properties of these enigmatic objects.
They give out gamma radiation as well as some incredibly low frequency sound waves, reaching up to 2 km in width
As far as we know.
