Question

is light can bend?explain

Answer 1

Yes light can be bent. The bending of light is called reflection of light. There is also one phenomenon known as refraction which deals with bending of light

Answer 2

Yes, light bends under the influence of a force.

If you're talking about refraction, light bends due to a change in its speed due to the optical density of a medium

If you talking about the bending of light under the influence of a force, like gravity, then yes, it happens, light bends or interacts with gravity, like near a black hole.
