Time for radio waves to reach moon?

Click For Summary
SUMMARY

Radio waves travel at the speed of light, approximately 300,000,000 meters per second. Given the average distance from Earth to the Moon is 384,000 kilometers, it takes about 1.28 seconds for radio waves to reach the Moon. This calculation is derived from the formula speed = distance / time, confirming the direct relationship between distance and the time taken for signal transmission.

PREREQUISITES
  • Understanding of the speed of light (300,000,000 m/s)
  • Basic knowledge of distance measurement in kilometers
  • Familiarity with the formula for speed, distance, and time
  • Concept of radio wave transmission
NEXT STEPS
  • Research the physics of electromagnetic waves
  • Learn about the applications of radio waves in communication technology
  • Explore the impact of distance on signal latency in telecommunications
  • Study the historical context of lunar communication technologies
USEFUL FOR

Astronomy enthusiasts, physics students, telecommunications engineers, and anyone interested in the principles of wave propagation and communication technology.

So I was thinking that radio waves travel at the speed of light, approximately 300,000,000 m/s.I was wondering how much time it would take if the average distance from Earth to the Moon is 384,000 km.

Well, how many kilometers are in 300,000,000 meters?
 
Using speed = distance / time, what do you get? If that doesn't help, where do you get stuck?
