Directions Q. No. 1 are based on the following paragraph. An initially parallel cylindrical beam travels in a medium of refractive index $\mu (I)={{\mu }_{0}}+{{\mu }_{2}}I,$ where ${{\mu }_{0}}$ and ${{\mu }_{2}}$ are positive constants and $I$ is the intensity of the light beam. The intensity of the beam is decreasing with increasing radius. The initial shape of the wavefront of the beam is -     AIEEE  Solved  Paper-2010
