Expert Solution
Concept and Principle:
  • A large gravitational source is capeable of bending the space around it. This will cause the light traveling in its gravitational field to deviate. 

 

  • The amount of deflection caused will be given by,

θ=2GMRc2

Here G is the universal gravitational constant, M is the mass of the source, R is its radius, and c is the speed of light.
