The frequency shift of radiation from the particle is found to increase abnormally as it crosses the Schwarzschild unit, r= 2m. The minimum fluctuation period min of intensity and frequency of radiation is found to lies between limits [(0.6msec)(M/M/0) n <[,OMM <(0.5m sec) (M/MO)] set by Sunnyvale (1) for maximally rotating hole.

Introduction The boundary of the region which is known as black holies formed by a wave front or null hyper surface which just does not escape to infinity. Its rays are asymptotically paralle1 and the area is asymptotically constant. Null rays inside this surface have no future end points but have past end points at the emission of the flash. No signal emitted inside it is allowed to escape to infinity and bring information about the interior of collapsed object. The presence of a black hole could be ascertained by investigating into its gravitational influence affecting the motion of other bodies. Particles of mass small in comparison to the mass of the black hole might come under the influence of its gravitational field and swallowed by it. Powerful radiation emission can take place in this process of accretion of particles into the black hole. Radiation emitted by such particles is propagated to a distant observer along null geodesics as long as wave lengths of the radiation are sufficiently small compared to the radius of the black hole. It is also possible that gas fallen gin the black hole could setup a shock wave whack might be a sources of x-rays or radio waves. The motion of the accreting particle is often assumed to be geodesic. Non- geodesic radial accretion has been considered by Hwang and Dykla (2) Geodesic accretion has been considered by various authors, for example, Davis, Ruffian, Price (3). They have calculated the energy radiated when a point test particle falls radically into a Schwarzschild black hole. Particles orbiting the black hole have been considered by Peters and Mathews (4). By using the full non-linear Einstein Theory, Zerilli (5) has calculated radiated energy from a particle falling strength into Schwarzschild black hole for Zero angular momentum. F.de. felice, L. Nobili and M.Calvni (6) have studied the effect of gravity on the electromagnetic radiation emitted by particles which move on bound orbits closed to a rotating black hole. In view of the importance of accretion as an astrophysical process associated with the detection and observation of black holes an attempt has been made here to determine the possible orbit of a particle spiraling down a kerr black hole and to study the effect of gravity on the radiation emission of such a particle. In sec. 2 expression for the convergence of null rays from a source commoving with the black hole is found out. Orbits for the emitter and
