The flip flop is sensitive only to the positive or negative edge of the clock pulse. So, the flip-flop toggles whenever the clock is falling/rising at edge. This triggering of flip-flop during the transition state, is known as Edge-triggered flip-flop. 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.

You may be wrong because your answer is not defined, what are you input applied?
