Light waves
Light waves are transverse: the particles vibrate in a perpendicular direction to the energy [transfer]

Properties of waves:
-
-Medium-the material through which a wave travels; can be solids, liquids, or gases
- Mechanical waves- require a medium to travel ( ex: sound)
- Electromagnetic waves- can travel through empty space ( ex: light)
- 3 ex of waves- sound, light, seismic
-
Transverse- a type of wave that moves the medium at a right angle to the direction in which the wave travels.
Longitudinal: a type of wave that displaces the particles of the medium parallel to the direction in which the wave travels

-
The difference between Sound waves and Light Waves are: Sound Waves require a medium where Light Waves do not require a medium:
-
-
- The speed of the sound waves depends on the medium that it travels through
- Are longitudinal waves consisting of compressions and rarefactions.
- Are of different frequencies, giving notes of different pitches.
- Do not travel far as their energy is dissipated easily.
-
-
- Travel with a speed of 3 *108 m/s.
- Are electromagnetic waves consisting of varying electric and magnetic fields.
- Are of different frequencies, resulting in different colors.
- Can travel through a much greater distance.
