Question

are sound waves part of the electromagnetic spectrum?
yes, they are just like light waves
no, sound waves are longitudinal waves

Explanation:

Sound waves are longitudinal waves that require a medium (like air, water, or solids) to travel. They are mechanical waves. The electromagnetic spectrum consists of electromagnetic waves (like light waves) which are transverse waves and can travel through a vacuum. So sound waves are not part of the electromagnetic spectrum.

Answer:

no, sound waves are longitudinal waves
