Query: Null Geodesics and Red-Blue Shifts of Photons Emitted from Geodesic
  Particles Around a Non-Commutative Black Hole Spacetime   We investigate the geodesic motion of massless test particles in the
background of a noncommutative geometry inspired Schwarzschild black hole. The
behaviour of effective potential is analysed in the equatorial plane and the
possible motions of massless particles (i.e. photons) for different values of
impact parameter are discussed accordingly. We have also calculated the
frequency shift of photons in this spacetime. Further, the mass parameter of a
non-commutative inspired Schwarzschild black hole is computed in terms of the
measurable redshift of photons emitted by massive particles moving along
circular geodesics in equatorial plane. It is observed that the the
gravitational field of a non-commutative inspired Schwarzschild black hole is
more attractive than the Schwarzschild black hole in General Relativity.
