Experiment with multiple instrument places all over the earth

  1. Jan 20, 2007 #1
    I want to design an experiment with multiple instruments places all over the earth in such a way that at any time, at least one of the instruments can observe the sun. What is the maximum separation of instruments permitted?

    I am really confused. Please help me with this!!

    Step one in solving a homework problem (same goes for the other threads you just started) is to draw a picture :smile:

    Ok! the sun will be visible from one hemispher for sure, am i right. So I think it should be 1/2 the circumference of earth.
