Understanding Clock Hands
A clock typically has three main hands: the hour hand, the minute hand, and the second hand. Each of these serves a specific purpose in telling time.
Length of the Hands
- The hour hand is the shortest hand, as it only needs to point to the hour markers on the clock face.
- The minute hand is longer than the hour hand. It indicates the minutes and requires more length to cover the larger distance between minute markers.
- The second hand is the longest hand on a standard clock. It moves continuously around the clock face to measure seconds. Its longer length allows it to sweep across the entire clock face and provide a clear indication of the passing seconds.
Why the Second Hand is the Longest
- The design of a clock often prioritizes visibility and functionality. Since the second hand needs to move quickly and cover more distance in a shorter amount of time compared to the other hands, it is designed to be the longest.
- The extended length of the second hand helps in precise timekeeping, allowing it to easily reach the outermost markings on the clock, which represent each second.
Conclusion
In summary, while the hour and minute hands are crucial for telling the time in larger intervals, the second hand's length and continuous movement make it the longest hand on a clock. Thus, the correct answer to the question is option 'B', the seconds hand.
