The clearest difference is in their speeds. Sound travels around 720 miles an hour at sea level. Light travels at 186,000 miles per second. That is it goes a foot in about a picosecond. Sound will go a foot in about one milisecond. Sound needs a medium like air or water to travel and is greatly effected by the medium. Light travels without much regard for its' medium or the lack of one. It is effected when going through glass and crystals. Light will bend and even separate into its constituent colors. Sound is produced mechanically. Light is caused by the electron activity in an atom. It can be mechanically generated but is an electronic activity. Sound occurs when molecules are excited by a repeated mechanical action. A speaker cone moving back and forth causes air pressure variations that our ear gathers and starts translating it into something our brains can deal with. Light happens when the atoms valence electrons are made to jump into a higher orbit and when they fall back down they give off a photon. It is light in a confusing quantum package that has the properties of both having mass and being an electromagnetic wave.

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.
How does light waves compare with sound waves?
Light waves are electromagnetic waves that move at the speed of light. Sound waves are compression waves that move through a medium (air, liquids, solids), with varying speeds according to the medium.
How do the velocities of a sound wave and electromagnetic wave compare to each other?
In air at sea level, the speed of electromagnetic waves isroughly 882 thousand times the speed of sound.
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.
What kind of wave's wavelength compare to a cell?
a sound waves wavelength compares to a cell by comparing the waves one by the other. cells compared to wavelength are electromagnetic waves lol:)
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
