Worked practice questions

The speed of an EM wave in vacuum equals:

  1. $1/\sqrt{\mu_0\varepsilon_0}$, approximately $3\times 10^8$ m/s
  2. $\mu_0\varepsilon_0$, the product of two constants here
  3. $\sqrt{\mu_0\varepsilon_0}$, the square root of the product
  4. $\mu_0/\varepsilon_0$, the ratio of the two constants directly
Show answer and solution

Correct answer: A. $1/\sqrt{\mu_0\varepsilon_0}$, approximately $3\times 10^8$ m/s

$c = 1/\sqrt{\mu_0\varepsilon_0} \approx 3\times 10^8$ m/s in vacuum.
