Lunar Laser Ranging (LLR) is the practice of measuring the distance between the surfaces of the Earth and the Moon using laser ranging. The distance can be calculated from the round-trip time of laser light pulses travelling at the speed of light, which are reflected back to Earth by the Moon's surface or by one of five retroreflectors installed on the Moon during the Apollo program (11, 14, and 15) … WebJan 15, 2024 · 0:00 / 0:15 Earth and Moon Size and Distance scale - with real-time light speed!

Speed of light from earth to moon? - Answers
WebThe distance to the Moon is calculated approximately using the equation: distance = (speed of light × duration of delay due to reflection) / 2. Since the speed of light is a defined constant, conversion between distance and time of flight can be made without ambiguity. WebThe Speed of Light travels at a speed of 186,000 miles a second or 700 million miles an hour. For scale, the distance from the Earth to the Moon is about 239,000 miles. This … they were very happy
