Explore Software Defined Radio: erratum EM waves

Example:
„They‘re both just different frequencies of EM waves. Higher, faster frequencies may manifest as visible light; lower frequencies may manifest as television signals, radio signals, or even sound.“

Sound is not an EM wave! Sound is a pressure wave in materials as air or water.
