Yes, all high energy types. The intensity of each ray depends on the type of black hole.
Ultraviolet, X-ray, Gamma
Often x-rays are used - matter falling into the black hole emits copious amounts of x-rays. However, it is also possible to detect the black hole indirectly by observing objects moving around it - and this may happen by observing just about any electromagnetic wave.
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
Ray is a descriptive term denoting an energy form that radiates from a source. Thus Sound rays, Light rays and so on. In common use, it often restricts itself to a confined beam, such as from a flashlight.
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
As a black hole.As a black hole.As a black hole.As a black hole.
The whole point of a black hole is that its gravity is so strong that nothing - not even a ray - can escape from its gravitational pull. However, it is theorised that Hawking radiation does escape from the event horizon. Not yet proven (May 2013).
The recent work by Professor Hawking wherein he described a thermodynamic interaction with the universe originating in quantum effects near the event horizon takes his name, "Hawking radiation". The nature of the radiation itself is described as a particle-antiparticle pair (produced by intense gravity from the black hole acting upon a virtual particle) or sometimes as a quantum tunneling effect from just inside the event horizon; the negative component of which gets "added" to the black hole and thus reduces its mass (radiates inward) while its counterpart radiates outward. It is also calculated to be a very weak form of radiation.
The only event that we know of, that might result in a black hole, is a Type II supernova.
The stellar black holes are the most common ones, as far as we know.
A UV light radiates energy in the form of electromagnetic waves with wavelengths shorter than those of violet light but longer than those of x-rays. The radiation is invisible to the human eye.
The ending first: We don't know. Please re-read that. OK, what are the conjectures? A Black hole leads to another, somewhat parallel universe. A Black Hole leads "nowhere". A Black Hole leads to a different type of singularity. A Black Hole leads eventually to another "Big Bang" in another dimension. A black hole leads to a parking lot in Gelsinkirchen, Germany. There are many more. Please re-read the first sentence.
The type of rays that come together are called convergent rays.
