Light defection due to a charged, rotating body

Understand

According to GTR and subsequent developments in the field, it is known that there are three factors namely mass, rotation and charge that can influence the space-time geometry.

• Accordingly, we discuss the effect of space-time geometry of a charged, rotating body on the motion of the light ray.
• We obtained the expression for equatorial defection of light due to such a body up to fourth order term.
• In our expression for defection angle it is clear that charge can influence the path of light ray.
