How does light bend under gravitational field(gravitational force), why?

Click For Summary
SUMMARY

Light bends under gravitational fields due to the curvature of spacetime, as described by Einstein's General Relativity, rather than being influenced by gravitational force in the traditional sense. While light is massless, it is affected by gravity because it follows the geometry of spacetime. The speed of light remains constant at approximately 3 x 108 m/s, regardless of gravitational influence, contradicting the notion that acceleration applies in the same way as it does for massive objects.

PREREQUISITES
  • Understanding of General Relativity
  • Familiarity with the concept of spacetime
  • Basic knowledge of the speed of light (c)
  • Awareness of gravitational fields and their effects
NEXT STEPS
  • Study Einstein's General Relativity and its implications on light behavior
  • Explore the concept of spacetime curvature and its effects on light paths
  • Investigate gravitational lensing and its observational evidence
  • Learn about the implications of massless particles in physics
USEFUL FOR

Students of physics, astrophysicists, and anyone interested in the fundamental principles of light and gravity.

As I have heard that light bends under the gravitational force. While according to formula "w=mg", gravitation acts on objects that have mass, but light has no mass if it is considered as photon nature.
And also if light bends under gravitational FORCE then light velocity must changes(acceleration produces) according to formula, "F=ma"(force acts on an object produces an acceleration in that object) while light has constant speed i.e. c=3x108m/s.
How will you satisfy me about my both upper statements?
