Abstract

Abstract: In this paper, we have considered the modification of general relativity and presence of extra matter part for the exploration of traversable wormhole solutions. In particular, we have considered the background of f ( R, T ) gravity under the effect of scalar field and electric charge, which play the role of additional matter part. The energy conditions are detected in the presence of both scalar field and electric charge and the results are compared. Further, the existence of photon spheres, due to the strong gravitational lensing, is examined and the formation of relativistic images is studied.
