Abstract
In this paper, we study the deflection angle of light by traversable wormholes, which are supported by the three-form fields. The specific forms of the redshift and shape functions that produce results compatible with the energy conditions at throat of the wormholes are used. Having used the well-defined parameter sets of the three-form wormholes, we investigate the photon geodesic motion under the effective potential of the wormhole background. As a result, we discover that the radius of the photon sphere is a very useful observable that is used to analyze the geometrical structures of a physical wormhole.
