No, light cannot reflect a black hole in the usual sense.
1. Black holes absorb light
A black hole has such strong gravity that nothing—not even light—can escape from within its event horizon. Once light crosses this boundary, it's gone. So a black hole doesn't reflect light like a mirror or shiny object does.
2. But black holes can be "seen" indirectly
While light can’t reflect off a black hole, it can be bent around it due to gravity, a phenomenon called gravitational lensing. This allows us to detect black holes by observing how they distort light from background objects.
3. Accretion disk emits light
Many black holes are surrounded by a superheated disk of gas and dust (called an accretion disk), which glows brightly. We often "see" black holes by detecting this radiation, not by any reflection.
So, to summarize:
No, light cannot reflect off a black hole.
But yes, we can observe the effects of a black hole on light nearby, mainly through gravitational lensing and emissions from material outside the event horizon.
