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.
