An antenna is specifically designed to "pick up" electromagnetic waves.
These are typically amplified and converted to electronic signals in some sort of circuit. That circuit can then provide a signal to another device to produce output. This happens with a radio when the antenna gets radio waves and they are converted to sound from the radio. Television, when the signal come through the air, is directly analogous but produces sound and a picture.
Technically, though we do not usually use the terminology, any electronic signal over a wire is an electromagnetic wave, so even a telegraph produces sound from an electromagnetic wave.

What are some changes that can be caused by electromagnetic energy?
Unlike sound electromagnetic waves can travel trough empty space
What are some changes that caused by electromagnetic energy?
Unlike sound electromagnetic waves can travel trough empty space
What three ways can differ electromagnetic waves from sound waves?
Electromagnetic waves are transverse in nature where as sound waves are longitudinal. Electromagnetic waves can pass even through vacuum but sound waves are mechanical waves that means it needs badly a material medium Sound waves can be sensed by ear where as electromagnetic waves are sensed by eyes.
Which is not a type of electromagnetic wave?
Sound waves aren't an electromagnetic wave. So aren't seismic waves. So aren't waves in the ocean, in your hair, or waves bye-bye.
Why can electromagnetic waves travel through space and not sound waves?
Sound waves need a physical material to carry them, but electromagnetic waves don't.
What does contrast electromagnetic waves with water and sound waves mean?
It means explain how electromagnetic waves are different than water and sound waves.
Sound is not part of the electromagnetic spectrum because?
because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....
Sound waves are examples of?
electromagnetic waves
What evidence is there that sound waves are all electromagnetic in nature?
I think you are confusing something. Sound waves, and electromagnetic waves, are two different types of waves.
What changes as electromagnetic waves change?
As an electromagnetic wave changes, so does its energy.
How much pollution does a electromagnetic wave cause?
Electromagnetic waves only cause sound pollution because they are sound waves.
What happens when transverse electromagnetic waves encounter cavity?
light waves or electromagnetic waves are transverse and sound waves are longitudinal
