What is the basic difference between light waves and sound waves?
Answer:
Probably the most fundamental difference between light waves and sound waves is that light is electromagnetic energy, while sound is mechanical energy. Additionally, sound waves are longitudinal and light waves are transverse waves. Lastly, light waves do not require a medium through which to travel. Sound waves, because the mechanical energy from the source is transferred into the medium, actually must have something to move through to carry the mechanical energy of the wave.
