SUMMARY

Light does bend when it passes near a black hole due to gravitational lensing, a phenomenon where the path of light is altered by the curvature of space caused by massive objects. When light is directed directly toward or emitted from a black hole, it does not bend; however, if it passes close to the black hole, its trajectory will curve. This bending occurs because photons travel along null geodesics, which are the generalization of straight lines in curved spacetime. The concept of gravity as a result of the curvature of space is a fundamental principle of Einstein's theory of relativity.

PREREQUISITES
  • Understanding of general relativity
  • Familiarity with the concept of geodesics
  • Knowledge of gravitational lensing
  • Basic principles of light and photons
NEXT STEPS
  • Research gravitational lensing and its applications in astrophysics
  • Study the concept of null geodesics in general relativity
  • Explore the implications of black holes on spacetime curvature
  • Investigate the relationship between mass and gravity as described by Einstein's theory
USEFUL FOR

Astronomers, physicists, students of general relativity, and anyone interested in the behavior of light in strong gravitational fields.

will light bend when it reach in front of a black hole?

Explain more please. I assume you mean "will the path of light bend" but that depends on the situation. If a beam of light is directed either directly toward or directly from a black hole, its path will not bend. If, however, it go past a dark hole, then, as happens any time light passes a mass, its path will bend.
 
directly from a black hole said:
If the light was shone directly FROM a black hole wouldn't the light actually bend right back into the black hole since nothing can escape a black hole not even light?
 
I was wondering, even though it appears that light bends, is it actually going in a straight line?
 
Will light blend? Why yes, yes it does!


Oh, bend... Well, it'll does that too (look up, for instance, gravitational lensing)

In a manner of speaking yes. Photons travel on what are celled null geodesics and geodesics are a generalisation straight lines in euclidean space.
 
I guess its not the light that bends. It should be the "space" or the path of light that bends in the vicinity of large mass. Light just treads the path ! Gravity itself the result of the tension of "space" due to heavy mass ! This is the essence of relativity !
