I’m wondering how long it takes for a radio message to travel from Earth to the moon and back. I’m interested in the time it takes for a radio signal to make the round trip journey. Is it a matter of seconds, minutes, hours, or days? I’m curious to know what the exact time frame is for a radio signal to make this journey. I’m also wondering if the time frame varies depending on the type of signal being sent. Any information on this topic would be greatly appreciated.
