sound:- mechanical wave , needs a medium , longitudinal wave
light:- not a mechanical wave , no need of medium , transverse wave

 Sound Waves are longitudinal while light waves are transverse.
Sound Waves are mechanical waves(Need a materialistic medium to travel in ) while light waves are non- mechanical waves
The speed of sound waves is less compared to light waves.

Sound waves has following characteristics
1. Mechanical Waves
2. Required material medium to propagate.
3. Thay are longitudinal and transverse both .
4. They have avg . speed of 340m/s in the air .
Light waves has following characteristics
1. Non -Mechanical waves .
2. Do not require material medium to propagate .
3. They are transverse waves .
4. They have avg. speed of 3,00,000 km/s in the air and in he vacuum also .
