Instrument used to measure distance between earth and moon
There are various instruments that are used to measure the distance between Earth and Moon. However, the most commonly used instruments are:
- Lunar Laser Ranging Experiment (LLRE)
- Radar
Lunar Laser Ranging Experiment (LLRE)
LLRE is a method used to measure the distance between the Earth and the Moon. This method was first introduced by Apollo astronauts in the early 1970s. The LLRE works by firing a laser beam from Earth to the Moon and then measuring the time it takes for the laser beam to bounce back to Earth. By knowing the speed of light, scientists can calculate the distance between Earth and the Moon.
The LLRE is considered as the most accurate method to measure the distance to the Moon, with an accuracy of about 1 cm.
Radar
Radar is another method used to measure the distance between the Earth and the Moon. This method involves sending out a radio signal from Earth towards the Moon and then measuring the time it takes for the signal to bounce back to Earth. Scientists can then use the time delay to calculate the distance between the Earth and the Moon.
The radar method is less accurate than the LLRE method, with an accuracy of about 100 meters.
Conclusion
Both LLRE and radar are important instruments for measuring the distance between Earth and Moon. However, LLRE is the most accurate method, while radar is less accurate but still useful in situations where LLRE cannot be used.
