FAQs on Clocks Video Lecture - SSC CGL Tier 2 - Study Material, Online Tests, Previous Year
| 1. What are the different types of clocks? |  |
Ans. There are several types of clocks, including analog clocks, digital clocks, pendulum clocks, and atomic clocks. Analog clocks have hour and minute hands, while digital clocks display the time numerically. Pendulum clocks use a swinging pendulum to keep time, and atomic clocks are the most accurate type of clock and rely on the vibrations of atoms to measure time.
| 2. How do analog clocks work? | |
Ans. Analog clocks work by using a set of gears and a power source, such as a battery or winding mechanism, to move the hour and minute hands. The gears transfer the power to the hands, causing them to rotate at different speeds. The hour hand completes one full rotation every 12 hours, while the minute hand completes one full rotation every hour.
| 3. What is the significance of atomic clocks? | |
Ans. Atomic clocks are highly accurate timekeeping devices that use the vibrations of atoms to measure time. They are considered the most precise clocks available and are used in scientific research, telecommunications, and global navigation systems like GPS. The accuracy of atomic clocks is crucial in fields where precise time measurements are essential, such as satellite communication and space exploration.
| 4. How do digital clocks display time? | |
Ans. Digital clocks display time numerically using electronic components, such as light-emitting diodes (LEDs) or liquid crystal displays (LCDs). These clocks rely on a quartz crystal oscillator to generate a precise electrical signal. The oscillator's vibrations are counted by a circuit, which converts them into the appropriate numerical format, allowing the clock to display the time digitally.
| 5. Can pendulum clocks be as accurate as atomic clocks? | |
Ans. No, pendulum clocks cannot be as accurate as atomic clocks. Pendulum clocks rely on the swinging motion of a pendulum to keep time, and their accuracy can be affected by various factors such as temperature, air resistance, and friction. On the other hand, atomic clocks use the vibrations of atoms, which are highly stable and consistent, making them far more accurate than pendulum clocks.
