Abstract: In this study, We correlated frequency bandwidth of 12 Type II bursts to the angular width of the associated CMEs and obtained an anticorrelation coefficient of ~ 60 % suggesting that the CMEs with large angular widths could produce narrow-band Type II emissions, in stark contrast to the recent report[1], that they produce broad-band Type II emissions. We further deduced the height of the Type II bursts (rType II ) at the onset time of the burst was < CME height (rCME), suggesting that the Type II emissions could be produced in the flank region of the shock rather than in the shock front
