# Chapter 6 - Electronic Structure of Atoms - Exercises: 6.15d

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).
