The electromagnetic waves travel with a velocity
1 equal to velocity of sound
2 equal to velocity of light
3 less than velocity of light
4 none of these
Explanation:
B The electromagnetic waves travel with a velocity equal to velocity of light. Velocity of electromagnetic waves $=\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}=3 \times 10^{8} \mathrm{~m} / \mathrm{s}=$ velocity of light
