@samiksha: because the flip flop is sensitive only to the positive or negative edge of the clock pulse....so the flip-flop toggles whenever the clock's falling/rising edge...thus the output curve has a time period twice that of the clock....frequency is inversely related to time period...and hence frequency gets halved.....got it??

J K flip flop o/p toggles if input is 1,1
