How do scientists look for black holes in space? describe what a black hole looks like using one of the different ways of seeing the sky?

Scientists can't observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. Scientists can infer the presence of black holes and study them by detecting their effect on other matter nearby.

Though we don't know 100% what black holes look like, scientists have theories. Black holes bend light. So the sky around a black hole will probably seem to distort around it.

i think they are all correct

explanation:

they seem good

wavelength divides in half and speed stays the same.
