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.
Information in transmitted in terms of energy transfer in a telephone?
Information is usually transmitted in terms of either radio waves or acoustic energy in a telephone. Machines such as the fax are usually used.
What does contrast electromagnetic waves with water and sound waves mean?
It means explain how electromagnetic waves are different than water and sound waves.
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.
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.
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
Is a sound wave a electromagnetic wave in nature?
No. Sound waves are mechanical waves.
The electromagnetic spectrum includes what?
The electromagnetic spectrum includes electromagnetic waves with a continuous flow of the wavelength.
