Seemingly simple question that I managed to be stumped on.

  1. Mar 24, 2012 #1
    This is in my grad electromagnetism class but it seems like a very simple question so I was unsure of where to post it.

    1. The problem statement, all variables and given/known data
    All the problem says is to evaluate the following (including units)

    [tex]\sqrt{\frac{\mu_0}{\epsilon_0}}[/tex]


    2. Relevant equations

    [tex]\frac{1}{\sqrt{\mu_0 \epsilon_0}}=c[/tex]

    3. The attempt at a solution

    So using the above formula, this is just simply [itex]\mu_0 c[/itex] which happens to equal around 376.7. The problem is, I do not know what this value is. is this a significant number? The units would be H/s.
    :confused:

    Yes it's a significant number. Hint: units H/s are equivalent to Ohms :wink:

    I did some internet searching and found an article explaining this. The article says it is called the "Impedance of free space." Gives a pretty good explanation :]

    Thanks!
