False. Correction: Electromagnetic radiation and sound waves travel at different speeds.

Work Step by Step

We know that all types of electromagnetic radiation travel at the same speed. However, since sound waves are not a type of electromagnetic radiation, they don't travel at the same speed as electromagnetic radiation. The statement is false. If you want a more detailed answer, the speed of sound waves in vacuum is 0m/s. In other words, sound cannot propagate through space. Even in air, the speed of sound waves is only 343m/s, much less than the speed of electromagnetic radiation ($2.998\times10^8$m/s in vacuum).
