Question

The speed of electromagnetic waves in vacuum is

• A. ${\mu }_0{\epsilon }_0$
• B. $\frac{1}{\sqrt{{\mu }_0{\epsilon }_0}}$
• C. $\sqrt{{\mu }_0{\epsilon }_0}$
• D. $\frac{1}{{\mu }_0{\epsilon }_0}$

Answer 1

Answer: (B)

The electromagnetic waves travel with the speed of light in vacuum and it is given as $c=\frac{1}{\sqrt{{\mu }_0{\epsilon }_0}}$
