The difference between Sound waves and Light Waves are: Sound Waves require a medium where Light Waves do not require a medium
Sound Waves
1. Require a medium.
2. Travel with a speed of 332 m/s at 0 C.
3. Are longitudinal waves consisting of compressions and rarefactions.
ADVERTISEMENTS:
4. Are of different frequencies, giving notes of different pitches.
5. Do not travel far as their energy is dissipated easily.
Light Waves
1. Do not require a medium
2. Travel with a speed of 3 *108 m/s.
ADVERTISEMENTS:
3. Are electromagnetic waves consisting of varying electric and magnetic fields.
4. Are of different frequencies, resulting in different colors.
5. Can travel through a much greater distance.
