**Electromagnetic Wave Speed Derivation from Maxwell's Equations**

Using Maxwell's equations, it can be shown that electromagnetic waves have a speed in free space of:

- \(\left( \epsilon_0 \mu_0 \right)^{-3/2}\)
  
  \( \circ \) 

- \(\epsilon_0 \mu_0\)
  
  \( \circ \) 

- \(\left( \epsilon_0 \mu_0 \right)^{-1/2}\)
  
  \( \circ \) 

- \(\left( \epsilon_0 \mu_0 \right)^{-1}\)
  
  \( \circ \) 

- \(\left( \epsilon_0 \mu_0 \right)^{-2}\)
  
  \( \circ \)

**Explanation:** 

- \(\epsilon_0\) is the permittivity of free space.
- \(\mu_0\) is the permeability of free space.

The answer can be derived from the relationship demonstrated through Maxwell's equations, specifically using physical constants for the speed of light \(c\) in a vacuum:
\[ c = \frac{1}{\sqrt{\epsilon_0 \mu_0}}. \]

The correct choice in this context is \(\left( \epsilon_0 \mu_0 \right)^{-1/2}\).
