Answer:
1. Sound is longitudinal waves, light waves is transverse
2. Sound is a mechanical wave, light is an electromagnetic wave
3. Speed of sound is less than the speed of light waves. For example, in air, sound travels at approximately 333.1 m/s, while light travels at about 3*10^8 m/s
4. Sound waves can't be plane-polarized while light waves can be polarized.
