Seemingly simple question that I managed to be stumped on.

[Xyius]

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

Homework Statement

All the problem says is to evaluate the following (including units)

$$\sqrt{\frac{\mu_0}{\epsilon_0}}$$

Homework Equations

$$\frac{1}{\sqrt{\mu_0 \epsilon_0}}=c$$

The Attempt at a Solution

So using the above formula, this is just simply $\mu_0 c$ 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.

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

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 :]
