  The paper deals with an extensive study of null and timelike geodesics in the
background of wormhole geometries. Starting with a spherically symmetric
spacetime, null geodesics are analyzed for the Morris-Thorne wormhole(WH) and
photon spheres are examined in WH geometries. Both bounded and unbounded orbits
are discussed for timelike geodesics. A similar analysis has been done for
trajectories in a dynamic spherically symmetric WH and for a rotating WH.
Finally, the invariant angle method of Rindler and Ishak has been used to
calculate the angle between radial and tangential vectors at any point on the
photon's trajectory.
